In a transformation experiment, donor DNA was obtained from a prototroph bacterial strain (x* y z'), and the recipient was a triple auxotroph (x y z). The following transformant classes were obtained: x*y z 160 130 x*y*: xy z x'y 190 170 3 1 5 x*y What general conclusions can you draw about the linkage relationships among the three genes?

During your experiment you analysed only a few of the recombinant clones for the presence of the highly repeated Aluelements. If you wanted to screen for a single-copy gene, you would need to screen a much larger genomic library. Assuming, that you already know the amino acid sequence of unicorn (a species with a similar physiology to humans) insulin, how would you construct a probe which would enable you to use nucleic acid hybridisation to screen a unicorn genomic DNA library for the insulin gene? Hint: you have access to any molecular biology reagents and equipment you might need, such as vectors, enzymes, and DNA sequencers.

If there is a mutation, what is the type of mutation (be as specific as possible) and explain the rationale for your decision. Assuming this is the only difference between the Wildtype and Strain X, describe the potential impact of the mutation on the structure and function of the protein.
An Hfr strain that is hisE + and pheA + was conjugated to a strain that is hisE − and pheA −. The conjugation was interrupted at different times, and the percentage of recombinants for each gene was determined by streaking on media that lacked either histidine or phenylalanine. The following results were obtained: A. Determine the map distance (in minutes) between these twogenes.B. In a previous experiment, it was found that hisE is 4 minutesaway from pabB and that PheA is 17 minutes from pabB. Drawa genetic map showing the locations of all three genes.

Two pathways, homologous recombination and nonhomologous end joining (NHEJ), can repair double-strandbreaks in DNA. If homologous recombination is an errorfree pathway whereas NHEJ is not always error free, whyis NHEJ used most of the time in eukaryotes?
DNA from a strain of Bacillus subtilis with genotype a + b + c + d + e + is used to transform a strain with genotype a – b – c – d – e – . Pairs of genes are checked for co-transformation and results shown below are obtained. Based on these results, what is the order of the genes on the bacterial chromosome? Show how you work out the order by diagraming.

In DNA-hybridization experiments on six species of plants in the genus Vicia, DNA was isolated from each of the six species, denatured by heating, and sheared into small fragments (W. Y. Chooi. 1971. Genetics 68:213–230). In one experiment, DNA from each species and from E. coli was allowed to renature. The graph shows the results of this renaturation experiment. Q. Notice that, for the Vicia species, the rate of renaturation is much faster in the first hour and then slows down. What might cause this initial rapid renaturation and the subsequent slowdown?
