Which of the following is not a feature of the repair of such gaps?

A. The 3' single-strand overhang invades the intact portion of the chromosome, pairs with its complementary strand, and displaces the other.
B. Strand invasion occurs by the intact, lesion-containing strand.
C. Branch migration generates two Holliday junctions.
D. The displaced, undamaged strand is replicated.
E. Holliday intermediates are cleaved by resolvases.
