Question

2. Ifthe at and b+ genes of E. coli are more frequently recovered together than at and ct in transformation experiments involving a- b-e- recipient cells, which of the following conclusions is most likely to be correct (one answer): (3 Points) A) a+ and a- are more closely linked than c+ and c- B) bt and c+ are more closely linked than a+ and b+ C) at and c+ are more closely linked than at and b+ D) b+ and b-are more closely linked than c+ and c- E) a+ and b+ are more closely linked than a+ and c+.

Explanation / Answer

Option E) is correct

Since a+ and b+ genes of E.coli are more frequently recovered together than a+ and c+ in transformation experiments, thus a+ and b+ genes are more closely linked than a+ and c+. Genentic linkage is the phenomenon wherein genes that are closer together on a chromosome are inherited together.
