Which of the Following Statements is True of Non- Homologous

Question

Which of the following statements is true of non- homologous end joining (NHEJ)?
A) it is error- prone
B) it is a double- strand repair pathway
C) it is error- free
D) it is both error- prone and is a double- strand repair pathway
E) it utilizes the sister chromatid as a template for repair

Accepted Answer

NHEJ is an error-prone process because it directly joins the broken ends without a template, leading to potential mutations or deletions. It is also a double-strand break repair pathway, repairing breaks without using a homologous template, unlike homologous recombination.
