15. Several mutants are isolated, all of which require com-pound G for growth. The compounds (A to E) in the bio-synthetic pathway to G are known, but their order in thepathway is not known. Each compound is tested for itsability to support the growth of each mutant (1 to 5). Inthe following table, a plus sign indicates growth and aminus sign indicates no growth.olord bos og elu Compound testedА ВB CDEGMutanf 1a. What is the order of compounds A to E in the pathway?b.

1. You are studying a biochemical pathway and isolate Neurospora mutants I, II, and III. Mutant I can grow if you supplement the medium with Z. Mutant Il can grow if you supplement the medium with X, Y, or Z. Mutant III can grow if you supplement the medium with X and Z, but not with Y. Draw a biochemical pathway that shows the correct order for compounds X, Y, and Z and for the enzymes that each mutant is defective for.
1. Construct one plot including the data for the WT and the MC4R mutants presenting the differences in membrane localisation. 2.Obtain approximate Emax and EC50 values from the graphs. 3.Why the ratio of PE/GFP fluorescence is measured in the FACS experiment, instead of measuring only total PE fluorescence? 4.Explain the effect that each mutation causes in the function of MC4R, and how they can be linked to disease.
A pure culture of an unknown bacterium was streaked onto plates of a variety of media. You notice that the colony morphologyis strikingly different on plates of minimal media with glucose compared to that seen on trypticase soy agar plates. How can you explain these differences in colony morphology? Also, describe what happens when a nonsense mutation is introduced into the gene encoding transposase within a transposon and why is it more likely that insertions or deletions will be more detrimental to a cell than point mutations?

The results of the fluctuation test (Fig. 7.5) were interpreted to mean that different numbers of mutantbacteria preexisted in each of the 11 culture tubes because the mutations arose spontaneously at differenttimes during the growth of each culture. However, another possibility is that the differences in the numberof colonies on the plates are simply due to differencesin the ability of the petri plates to support the growthof colonies. For example, perhaps the selective agentor the nutrients in the media were not evenly distributed in the molten agar poured into the petri dishes.What experiment could you do to determine whetheror not differences in the petri plates were a factor inthe experiment?
nich TWO of the following statements about Extended Spectrum ß-lactamases are CORRECT? O Extended Spectrum ß-lactamases can inactivate all B-lactam antibiotics except third generation antibiotics in this family. O Genetic material encoding for extended spectrum ß-lactamases are easily transferred to other bacteria via transduction. O Extended Spectrum ß-lactamases are frequently produced in Klebsiella sp. and Escherichia coli strains. O Many Extended Spectrum ß-lactamases are not inhibited by clavulanic acid and other B-lactamase inhibitors. OSome Extended Spectrum ß-lactamases-producing E. coli are still sensitive to penicillins. OA new class of Extended Spectrum ß-lactamases has emerged and these have been widely detected among S. epidermidis. O Extended Spectrum ß-lactamases are not effective against the cephalosporin family of antibiotics.
