Which of the Following Repair Pathways Can Accurately Repair a Double-Strand

Question

Which of the following repair pathways can accurately repair a double-strand break?
A) Base excision repair
B) Nucleotide excision repair
C) Direct chemical reversal
D) Homologous recombination
E) Nonhomologous end joining

Accepted Answer

Compared to the faithful homologous recombination pathway to repair double-strand breaks, nonhomologous end joining is a "quick and dirty" solution that often results in mutations at the site of repair.
