By introducing a new gene into an organism via a vector (DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell) (plasmid, virus, etc.) Test. AP Biology, MODS 19-21. Subjects: Science, Biology, General Science. This transformation usually occurs within plasmids, which are small circular DNA molecules separate from its chromosome. Gene regulation allows for adaptation to different conditions and prevents wasteful overproduction of unneeded proteins. Bacteria are a whitish color. The best way is to compare the control to the experimental plates. Transformation is the process by which a bacterium takes up and expresses exogenous DNA, resulting in a newly acquired genetic trait that is stable and heritable. What advantage would there be for an organism to be able to turn on or off particular genes in response to certain conditions? Which of the traits that you originally observed for E. coli did not seem to become altered? Instead of having students answer the "cookbook" pre-lab and post-lab questions where they can find the answers online, I have them write a formal lab report.The resourc. Based on the above considerations, which would be the best choice for a genetic transformation: a bacterium, earthworm, fish, or mouse?

Thus you will see only individual colonies on the plate. Describe how you could use two LB nutrient agar plates, some E. coli, and some ampicillin to determine how E. coli cells are affected by ampicillin. 1. a green fluorescence protein GFP. If ampicillin has no effect, there should be approximately equal numbers of colonies on both plates. The growth of E. coli on the two plates could be compared. There can be 10 to 200 copies of the same plasmid within a cell. In the lab, we incorporated the plasmids into the bacteria and put them into a medium with an antibiotic. This is done through electrophoresis. Title: pGLO Transformation Lab Introduction: Genetic transformation is a change caused by genes, involving the insertion of a gene into. The colonies on the LB/amp/ara plate fluoresce green under UV light, and the transformed colonies can grow on ampicillin resistance. Students discover and explore the process of 0 0. The pGLO plasmid DNA and the original bacteria can be eliminated from providing the fluorescent source. LabBench Activity Analysis of Results I. pGlo plasmids, when taken up by a bacteria, will code for. This experiment involved four different scenarios of bacterial cells on agar plates. Get a verified writer to help you with Experiment on Bacteria Transformation. 24 2. A successful experiment will be represented by the presence of colonies on the (+) pGLO LB/amp and (+) pGLO LB/amp/ara plates and the absence of colonies on the (-) pGLO LB/amp plate. Attleboro, MA 02703 (508) 222-5150 ext. They also can explore answers to questions about plasmids and transformation that might have been raised during the initial investigation. Good examples of highly regulatable genes are the enzymes which break down carbohydrate food sources. If a white colony was streaked onto an LB/amp/ara plate, the resulting colonies would be green.

Key Concepts: Terms in this set (34) What is the total volume of reagent in mL? Can you explain why the bacterial cells' outer cell wall ruptures when the cells are frozen? Gravity. The organism should not be able to infect plants or animals. The bacteria need to be ruptured in order to release the GFP/plasmid DNA, which can then be purified using column chromatography. Required Lab Report for BIO281. Since only some of the cells exposed to the amp R plasmids will actually take them in, only some cells will be transformed. The UV light is necessary to cause the GFP protein within the bacteria to fluoresce. Gravity. To genetically transform an entire organism, you must insert the new gene(s) into every cell in the organism. 2. Student involvement in this process will result in an increased understanding of the scientific process and the value of proceeding into a task in an organized and logical fashion. Genetic transformation occurs when a cell takes up and expresses a new piece or foreign ____________, often a circular plasmid. Bacterial Transformation Lab Answers bacterial plasmid-based genetic transformation, enables students to manipulate genetic information in a laboratory setting to understand more fully how DNA operates. Moreover, the colonies on the LB/amp/ara plate should fluoresce green. study of biological processes, observation of cell movement, use of GFP as a visual marker. These bacteria were removed from the starter plate, did not have any plasmid added to them, and were replated on an LB plate. The multiplication of a single bacterium on agar plates appears as a colony. This document contains the questions for this lab that are also included in the Bacterial Transformation Lab PDF. Both types of bacteria (those that are ampicillin resistant and those that are ampicillin sensitive) look similar when cultured—think about the colonies on the LB starter plate and the colonies on the +pGLO LB/amp plate. In the transformation lab, we discovered the process of bacterial genetic transformation and how to calculate transformation efficiency. PLAY. Abstract.

In the space below, list these non-transformed traits and how you arrived at this analysis for each trait listed. Match. Each colony can be seen by the naked eye, while a single bacterium requires a micro-scope for observation. This document contains the questions for this lab that are also included in the Bacterial Transformation Lab PDF. Before any change in the phenotype of an organism can be detected, a thorough examination of its usual (pre-transformation) phenotype must be made. The color of colonies, number of colonies, distribution of colonies on the plate. Conversely, if arabinose is not present in the nutrient media, it would be very energetically wasteful to produce the enzymes to break down arabinose. From your results, can you tell if these bacteria are ampicillin resistant by looking at them on the LB plate? Bacterial Transformation Lab Report: Transforming E.coli strains with Green Fluorescent Protein. Created by. "After transformation, four different plates were streaked with bacteria. Cells which were not treated with DNA (-pGLO) should not be expressing the ampicillin resistance gene and will not grow on the LB/amp plates. If there is no ampicillin in the agar, E. coli will cover the plate with so many cells it is called a "lawn" of cells. What does this observation indicate about the source of the fluorescence? The sugar arabinose in the agarose plate is needed to turn on the expression of the GFP gene. Transformation is the introd… Describe the evidence that indicates whether your attempt at performing a genetic transformation was successful or not successful. Bacterial Transformation Lab Report. Colony size is similar both before and after transformation. University. We transformed E.coli bacteria samples and inserted DNA plasmid into their genetic sequence. The bacteria that did not receive the plasmid are growing on a plain LB plate. This Site Might Help You. Cells which were treated with DNA (+pGLO) should contain the pGLO plasmid and should express the ampicillin resistance gene—the corresponding LB/amp plate will contain transformed bacterial colonies. Be sure to. 1285 Bacterial Transformation Virtual Lab - A.P. This could be a result of not adding a loopful of plasmid to the (+) pGLO tube or not adding a colony of bacteria to the (+) pGLO tube. The (-) pGLO LB/amp plate shows that the starter culture does not grow on the LB/amp plate. Bacterial Transformation Lab Review. Roanne. What do you think each of the two environmental factors you listed above is doing to cause the genetically transformed bacteria to turn green? When a bacterial cell freezes, the volume of cytoplasm expands. If the bacteria are viable on the LB/amp plate, then they are resistant to ampicillin. A bacterium would be the best host organism. Safety is another important consideration in choosing an experimental organism. The organism should not produce any toxins or compounds which could make people sick. Equal amounts of cells could be plated on two different LB nutrient agar plates, one which contains just LB nutrient agar and one which contains LB nutrient agar ampicillin. Bacterial Transformation Lab: pGLO. From the results that you obtained, how could you prove that these changes that occurred were due to the procedure that you performed? Yes. Recall what you observed when you shined the UV light source onto a sample of original pGLO plasmid DNA and describe your observations. record your answers in your laboratory notebook. If the genetically transformed cells have acquired the ability to live in the presence of the antibiotic ampicillin, then what can be inferred about the other genes on the plasmid that were involved in your transformation procedure? A control plate is a guide that is used to help you interpret the experimental results. The sugar arabinose turns on expression of the GFP gene by binding to a regulatory protein, araC, which sits on the PBAD promoter. 0.250mL or 250 microliters. Explain your answer. The expansion puts pressure on the weakened cell wall, which then ruptures from the pressure. Explain your prediction. 5 years ago. This usually occurs with plasmids, small circular molecules of DNA.

Do you observe some E. coli growing on the LB plates which do not contain ampicillin/arabinose? Created by. Cells that were not treated with the plasmid (LB/amp (-) pGLO and LB/amp/ara (-) pGLO plates) could not grow on ampicillin, whereas cells that were treated with the plasmid (LB/amp (+) pGLO and LB/amp/ara (+) pGLO plate) can grow on the LB/amp plate. This plate does not contain arabinose which is needed to induce expression of the GFP gene and generate green fluorescent colonies. What would you expect your experimental results to indicate about the effect of ampicillin on the E. coli cells? If a green colony under UV light was streaked onto an LB/amp plate, the resulting colonies would be white with no fluorescence. Can you predict what would happen if you took one of the green colonies from the LB/amp/ara plate and streaked it onto an LB/amp plate? 2017/2018. Although the E. coli strain used in these experiments has been rendered non-pathogenic, it is important to teach the students good sterile technique and safe disposal of bacteria. Woodstock High School, Woodstock • SCIENCE 1035B, Truckee Meadows Community College • BIOLOGY 190, Isaac Perez Quintero - Transformation lab.pdf, University of California, Davis • BIOLOGY 2A. The bacteria we might generally call "bad" for us include those responsible for causing illnesses like food poisoning. Thus, there should be few, if any, bacterial colonies present on the ampicillin plate. The LB/amp control plate can be compared to the LB/amp (+)pGLO plate. This is a lab report assignment to accompany the pGLO Bacterial Transformation Lab done in many AP Bio and Biotechnology classes. When they drop down to a lower energy state they emit a longer wavelength of visible fluorescent green light at 509 nm. Write. Which plates should be compared to determine if any genetic transformation has occurred? The theory we have learned in class is that the naked DNA is then integrated into the bacterium's DNA, causing the expression of new traits. Without bacteria, we would not be able to digest food or produce some of our favorite foods such as yogurt and cheese. (Possible answers: E.coli within the intestines of mammals, bacteria within the soil, bacteria used to make foods such as yogurt.) The questions go in the same, order that they are asked in the PDF so make sure to answer these questions while you read, 1. I just need help with formulating the hypotheses. 1 Bacterial Transformation 1. STUDY. Course Hero is not sponsored or endorsed by any college or university. To ensure a pure culture, we must start with a single bacterium. List those traits below and describe the changes that you observed. You cannot tell if the bacteria are ampicillin resistant just by looking at them. What was the purpose of rupturing or lysing the bacteria? Explain your answer. To dispose of contaminated material: Immerse all disposable pipets, tubes, and loops that have come in contact with bacteria in 10% bleach solution for at least 20 minutes before draining, rinsing and disposing of in the trash. This comparison shows that genetic transformation produces bacterial colonies that can grow on ampicillin (due to the uptake of the pGLO plasmid and the expression of the ampicillin resistance gene). State the purpose of each component of the experiment, inhibits cell growth by interfering with cell wall synthesis, regulate Green Fluorescent Protein (GFP) expression in transformed cells, transforms bacteria that is used to make a cell competent, increases, possesses the ability to absorb blue light and in response show green, Substance that allows bacteria to recover before being plated. What is meant by the control plate(s)? This plate contains arabinose which induces expression of the GFP gene and generates green fluorescent colonies. This exogenous DNA can be recombinant DNA molecules that have been constructed in vitro, as well as natural DNA molecules. Classzone Bacterial Transfomation Virtual Lab Answer Key Antibiotics usually kill bacteria (are bacteriocidic) or inhibit their growth (bacteriostatic). The ara control region regulates GFP expression by the addition of arabinose, so the GFP gene can be turned on and off by including or omitting arabinose from the culture medium. The questions go in the same order that they are asked in the PDF so make sure to answer these questions while you read the lab PDF. (Hint: one factor is in the plate and the other factor is in how you look at the bacteria). Addresses AP® Biology Big Ideas 1 and 3 and Essential Knowledge 1.A.1, 1.A.2, 3.A.1, 3.C.1, and 3.C.2. To get this information, which would be a better candidate for your investigation, an organism in which each new generation develops and reproduces quickly, or one which does this more slowly? 1. In this experiment, bacteria will be transformed with a gene that codes for Green Fluorescent Protein (GFP). What is the function of the “-DNA” tube. Fast production of offspring or new progeny will allow you to quickly assess if the new trait has been passed on. E. coli colonies you initially observed? On which of the plates would you expect to find bacteria most like the original nontransformed. Which of the two possible sources of the fluorescence can now be eliminated? This lab also explored the effect that certain environments would have on the bacteria, including those containing antibiotics or certain sugar molecules, as well as how the introduced gene would interact with these environments. Bacteria are small, single-celled organisms which reproduce quickly and easily. Why? The (-) pGLO/LB control plate can be compared to any of the LB/amp plates to show that plasmid uptake is required for the growth in the presence of ampicillin. How would you change the bacteria's environment to best tell if they are ampicillin resistant? Providing publishers with the highest quality, most reliable and cost effective editorial and composition services for 50 years. STUDY. Why? The best test would be to take some of the bacteria growing on the LB plate and streak them on an LB/amp plate. Bacterial Transformation LAB Analyzing Results. Share. RE: bacterial transformation lab help? A bacterial colony is a large group or cluster of bacterial cells that originated from a single, clonal cell. Bacteria transformation is the process of a bacterium absorbing and integrating naked DNA located on the surface of their membrane. The presence of any colonies on the ampicillin plate would suggest that those bacteria are resistant to the antibiotic ampicillin. The plasmid must express a gene for ampicillin resistance (the protein product of the bla gene codes for beta-lactamase, the protein that breaks down ampicillin). The source of fluorescence is probably from some protein that the plasmid encodes from the addition of arabinose, namely GFP. Bacteria which resemble the non-transformed will be found on the LB/(-) pGLO plate. Thus, the plasmid must confer resistance to ampicillin. Scientists often want to know if the genetically transformed organism can pass its new traits on to its offspring and future generations. Describe your reasoning. Terms in this set (12) What is bacterial transformation? Only transformed cells can grow on agar with ampicillin. This document contains the questions for this lab that, are also included in the Bacterial Transformation Lab PDF.

To get acquainted with bacterial transformation applications in society. When arabinose is present, it binds to araC, consequently changing the conformation of araC which facilitates transcription of the gene by RNA polymerase (see detailed description in Appendix D). Write. What purpose does a control serve? Recall that the goal of genetic transformation is to change an organism's traits (phenotype). PLAY. Thus, they are virtually identical to the non-transformed starter colonies. If the sugar arabinose is present in the growth medium it is beneficial for bacteria to produce the enzymes necessary to catabolize the sugar source. This is why you remain in the best website to look the incredible book to have. Flashcards. Genetically transformed cells have taken up the pGLO plasmid which expresses the ampicillin resistance gene—these cells can survive on the plates which contain ampicillin. Arizona State University. 1. mocha_dog529. Explain your prediction. List all observable traits or characteristics that can be described. Comments.
