In E.coli,which protein(s)are necessary for the cell to recognize double-stranded breaks and conduct recombination during meiosis?
A) RecG
B) RecA
C) RecBCD
D) RuvABC

Question

Quizplus · Accepted Answer

RecBCD is a complex protein involved in the recognition and processing of double-stranded breaks during DNA recombination. RecA and RecG are also involved in recombination, but they do not specifically recognize double-stranded breaks. RuvABC is involved in the final stages of resolution of recombination intermediates, but is not directly involved in recognition of double-stranded breaks. Therefore, the best choice is C, RecBCD.
