In Homologous Genetic Recombination, RecA Protein Is Involved In

In homologous genetic recombination, RecA protein is involved in:

A) formation of Holliday intermediates and branch migration.
B) introduction of negative supercoils into the recombination products.
C) nicking the two duplex DNA molecules to initiate the reaction.
D) pairing a DNA strand from one duplex DNA molecule with sequences in another duplex, regardless of complementarity.
E) resolution of the Holliday intermediate.
