A Deleterious Mutation in RecA Results In

Question

A deleterious mutation in recA results in
A) a decrease in specific recombination.
B) a decrease in homologous recombination.
C) an increase in homologous recombination.
D) no change in either general or specific recombination.

Accepted Answer

RecA is crucial for homologous recombination, a process that repairs DNA damage by exchanging nucleotide sequences between similar or identical molecules of DNA. A mutation in recA would impair this function, leading to a decrease in homologous recombination.
