Which of the following is not true of repairing double-strand breaks by recombination?

A. After invasion of the homologous chromosome, the 3' end of the invading strand acts as a primer for DNA synthesis.
B. The broken ends are processed, with the 3'-ending strand selectively degraded to create 5' overhangs.
C. The 3' single strand extensions invade the homologous chromosome, displacing the homologous strand and base pairing with the complementary strand.
D. As a result of the two strand invasions, the two homologues are linked at two places and are called a branched intermediate.
E. The enzymes required for strand invasion belong to a class of proteins called recombinases.
