A double-stranded breakage repair pathway that requires the presence of a second chromosome carrying the same sequence of genes as the damaged chromosome is called _________.
A)nonhomologous end joining repair
B)homologous recombination
C)NHEJ
D)DNA methylation repair
E)nonhomologous recombination

Question

Quizplus · Accepted Answer

Homologous recombination involves the use of a second, homologous chromosome to repair double-stranded breaks. Nonhomologous end joining repair (NHEJ) does not require a homologous chromosome and instead directly joins the broken ends together. DNA methylation repair and nonhomologous recombination are not established repair pathways.
