One function of the RecA protein in recombination events is to:

Question

Quizplus · Accepted Answer

The RecA protein catalyzes the ATP-dependent DNA strand exchange reaction, which is the process by which homologous recombination occurs. This involves the invasion of a single strand of DNA from one molecule into a complementary region of another double-stranded DNA molecule. RecA helps facilitate this process by binding to single-stranded DNA (ssDNA), promoting strand invasion, and catalyzing the exchange of DNA strands.

Note: Choices A and B are incorrect because they refer to other proteins involved in recombination events (Endonuclease I and the RecBCD complex, respectively). Choice C is incomplete, as while RecA does play a role in initiating recombination, its specific function in this regard is through the strand exchange reaction. Choice E is also partially correct, as RecA does drive branch migration and process the Holliday junction, but this is part of the overall strand exchange reaction rather than a separate function.
