The synthesis of arginine by Nuerospora was determined by examining a number of
mutant strains that were unable to synthesize the compound. Use the table of
bacterial growth below to 1) determine the correct sequence of the synthesis pathway
and 2) where in the synthesis pathway each mutation interrupts the synthesis. A “+"
indicates growth.

true or false?
In their Nobel Prize-winning experiments, Beadle and Tatum exposed fungal spores to X-rays to induce mutations. If the mutants had mutations in the arginine metabolic pathway, they would grow in ------minimal medium (wrong answer), but NOT in -------complete medium (wrong answer).

- Why is it important to use a hyperthermophilic DNA polymerase in PCR? a) Because only hyperthermophiles have DNA polymerases. b) Because hyperthermophilic DNA polymerase is able to resist the saline reaction conditions. c) Because hyperthermophilic DNA polymerase is faster than other polymerases. d) Because hyperthermophilic DNA polymerase is able to resist denaturation at 95℃.arrow_forwardAs a clinical microbiologist, your job is to identify an infectious bacterial strain isolated from a patient. Phenotypically, you have discovered that the new bacterial strain can grow in the presence or absence of oxygen. By growing the strain in glucose carbohydrate tubes, you found that the organism is positive for glucose fermentation. After genome sequencing and biochemical analysis, you know that your organism is capable of making all of the enzymes necessary for glycolysis, and that it contains a TCA cycle and an electron transport chain.arrow_forwardBacillus thuringiensis makes toxins that kill insects. These toxins must be applied several times during the growth season to prevent insect damage. As an alternative to repeated applications, one strategy is to apply bacteria directly to leaves.However,B. thuringiensis does not survive very long in thefield. Other bacteria, such as Pseudomonas syringae, do survive.Propose a way to alter P. syringae so it could be used as an insecticide.Discuss advantages and disadvantages of this approach compared with the repeated applications of the toxins from B. thuringiensis.arrow_forward

- In your laboratory, you have an F− strain of E. coli that is resistantto streptomycin and is unable to metabolize lactose, but it can metabolizeglucose. Therefore, this strain can grow on a medium thatcontains glucose and streptomycin, but it cannot grow on a mediumcontaining lactose. A researcher has sent you two E. colistrains in two separate tubes. One strain, let’s call it strain A, hasan F′ factor (an F prime factor) that carries the genes that are requiredfor lactose metabolism. On its chromosome, it also has thegenes that are required for glucose metabolism. However, it is sensitiveto streptomycin. This strain can grow on a medium containinglactose or glucose, but it cannot grow if streptomycin is addedto the medium. The second strain, let’s call it strain B, is an F−strain. On its chromosome, it has the genes that are required forlactose and glucose metabolism. Strain B is also sensitive to streptomycin.Unfortunately, when strains A and B were sent to you, thelabels had fallen…arrow_forwardYou got an opportunity to join a professor lab who is working in-vivo model and specifically looking at the dysregulation of mitochondria in liver. He asked you to isolate mitochondria from a Rat liver and placed in an assay medium. Based on the knowledge you gain in this course so far, please answer the following questions: a) Which technique will you use to isolate mitochondria? b) What happens to the pH of the medium when the medium is kept anaerobic? c) What happens when O2-saturated saline is added to the mixture?arrow_forwardHow can i explain my answers in depth in microbology for example this question: Assume that there are horizontal gene transfers between two completely different bacterial species. In one case it is a plasmid that is transferred via conjugation, in the other case it is a part of the bacterial chromosome that is transferred via transformation. In which of the two cases is it most likely that the transferred DNA will remain and be able to function in the recipient cells? Explain the biological background to your answer .
