We isolate DNA from a bacteria that is wild type for the genes arg leu and his shear it in a blender mix it into a culture of bacteria that is mutant for the genes arg leu and his . We then plate on various media. These are the results: Media with arginine 20 colonies /ml Media with histidine 300 colonies /ml Media with leucine 500 colonies /ml Media with all three 10000 colonies/ml 21. What is this experiment called? A. transpiration B. conjugation C. transformation D. transduction
When Avery and his colleagues had obtained what was concluded to be the transforming factor from the IIIS virulent cells, they treated the fraction with proteases, RNase, and DNase, followed in each case by the assay for retention or loss of transforming ability. What were the purpose and results of these experiments? What conclusions were drawn?
Choose 1 or more than 1 RNA are extracted from liver cells and separated in agarose gel by electrophoresis side-by-side with a molecular weight marker. The separated RNA fragments are then transferred to an RNA-binding membrane. Next, this membrane is incubated with labelled probe specific for the gene X. This experiment determines: how many copies of gene X there are in liver cells. if the gene X is translated in liver cells. if gene X has a point mutation in liver cells. the chromosomal location of gene X. the length of the transcript of gene X.
In your opinion, is antibiotic use at farm sites promote the development and spread of antibiotic resistant genes in bacteria? Why or why not please explain based on the article
Three mutations were obtained in a bacterial gene. An antibody is available for the protein product of this gene. Both Northern analysis (RNA separated by electrophoresis, blotted, and probed with DNA) and Western analysis (proteins separated by electrophoresis, blotted, and probed with antibodies) were performed on the mutants. The results are summarized below. Northern Size Western Size 1 2 3 1 2 3 + Long Short Short Long For each mutation, what kind of mutation occurred and how do you know? a) Mutant 1 b) Mutant 2 c) Mutant 3
What is the purpose of the rat liver extract in this procedure?
As the leading scientist in a biomedical science laboratory, it is a requirement to give advice to your lab assistants when they are having problems with their experiments. What advice would you give to your assistants that are having the following problems: After performing a polymerase chain reaction (PCR) and agarose gel electrophoresis to confirm the presence of the C01 gene of 750bp. 2.1. They observe no band appearing on an agarose gel. What would be your conclusion? 2.2. They observe three bands of different sizes that resemble a smear on the gel. Advice 2.3. They observe a single band on the gel and conclude that the PCR product is an exact copy of the original template DNA. Would you support their condusion? Explain. 2.4. Explain how PCR can be used to detect infectious agents in diagnoses of diseases.

Why do some cells grow on the control plate in the absence of a mutagen?
Please answer the following questions using numbers and not text. For example, if you think the answer is 24, write 24 and not twenty-four. If you think the answer is 24 ATP, write only the number 24. As a microbiology technician, your job is to characterize a novel bacterial strain isolated from insects. Phenotypically, you have discovered that the new bacterial strain can grow in the presence or absence of oxygen. After genome sequencing and biochemical characterization, you know that your new organism is capable of making all of the enzymes necessary for glycolysis and the TCA cycle, and that it has an electron transport chain. Answer the following questions based on the growth of your organism on minimal media plates containing only acetate as a carbon and energy source. Acetate is transported across the membrane at the cost of 3 ATP per molecule. Each question should be answered based on the metabolism of one molecule of acetate. If you come up with a negative value, indicate an…
