During Generalized Recombination, ________ Proteins Catalyze Branch Migration at Crossovers

Question

During generalized recombination, ________ proteins catalyze branch migration at crossovers called ________.
A) RuvAB; Holliday junctions
B) RuvAB; duplexes
C) RecBCD; Holliday junctions
D) RecBCD; duplexes
E) RecA; duplexes

Accepted Answer

During generalized recombination, RuvAB proteins catalyze branch migration at crossovers called Holliday junctions. RecBCD is responsible for processing the DNA ends to generate single-stranded overhangs, while RecA plays a key role in the strand invasion step of recombination.
