The CRISPR system
A. facilitates homologous recombination through a complex system of proteins and clustered repeats.
B. recognizes foreign DNA sequences that have previously entered the cell and directs the Cas proteins to destroy them.
C. repairs DNA and increases DNA damage tolerance during times of stress.
D. synthesizes gene transfer agents during stationary phase.
