Rank these events in the order that they occur during the repair of 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 5’-ending strand selectively degraded to create 3’ 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.
