Exercise 9

Homologous Recombination. Bacterial cells use at least three different pathways for carrying out genetic recombination. One of these three pathways utilizes an enzyme complex called RecBCD, which binds to double-strand breaks in DNA and exhibits both helicase and single-strand nuclease activities. Briefly describe a model showing how the RecBCD enzyme complex might set. the stage for genetic recombination.
