Question

Suppose a researcher conducts matings between three Hfr bacterial strains and an F strain. The table shows the order in which genes are incorporated for each strain. Determine the gene order of the chromosome by placing each gene on the outside of the circular chromosome map. Identify the origin of replication for each Hfr strain on the inside of the map to indicate polarity of the origin. Hfr strain Order of gene transfer ikvqw izrbm vkimb 3 Answer Bank Answer Bank

Answer 1

The linear order gene is --- zbmikvqwtr

for hfr 1 the origin region - i

for hfr 2 the origin region - t

for hfr 3 the origin region - v
