You perform a cotransduction experiment using a donor strain that is D+ B+ C+ and a recipient strain Show more You perform a cotransduction experiment using a donor strain that is D+ B+ C+ and a recipient strain that is D- B- C-. Selecting for recipients with the D+ allele you find transductants in the following numbers: B- C- 108 B+ C- 77 B- C+ 0 B+ C+ 35 Determine the cotransduction frequency for all three pairs of genes if possible. You decide to examine another gene in the same bacteria gene A. The donor is A+ and the recipient is A-. You find transductants in the following numbers: D- B- C- 163 D- B- C+ 61 D- B+ C- 0 D- B+ C+ 28 D+ B- C- 0 D+ B- C+ 0 D+ B+ C- 0 D+ B+ C+ 0 Draw a map of the region of the chromosome containing these four genes including cotransduction frequencies for each pair you have been able to calculate from both parts of the question. You find an Hfr strain of this same bacterial. Interrupted mating experiments show that B is the first gene to enter the recipient cell followed by C. Draw this strains Hfr origin of transfer on your map. Be sure to indicate direction of transfer. Show less
