Which of the Following Molecules Carries Out Single-Strand Assimilation

Question

Which of the following molecules carries out single-strand assimilation?
A) XPA
B) MutD
C) RecA
D) RecBCD
E) UvrD

Accepted Answer

RecA is known to carry out single-strand assimilation, also called strand invasion. This process is essential for homologous recombination, where a single-stranded DNA molecule invades a double-stranded DNA molecule to initiate the exchange of genetic information. XPA, MutD, RecBCD, and UvrD are involved in other DNA repair and maintenance processes.
