- You have a 20 mg/ml of Ethidium bromide stock solution. You need to a final concentration of 2ug/ml into a Agarose solution to visualize DNA. What is the dilution factor? Give typing answer with explanation and conclusionPlease 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…Why were radioactive sulfur and phosphorous used to label bacteriophage in Hershey and Chase's experiments?
