Question

RuvAB:

can promote branch migration but the process is very slow.
contains two donut-shaped RuvA hexamers, related in structure to DnaB helicase, that have nuclease activity.
cleaves the Holliday intermediate by replacing one RuvA with RuvC.
can reload DnaB helicase to reprime DNA replication after repair.
does not require ATP hydrolysis.

Answer 1

The correct answer is "cleaves the Holliday intermediate by replacing one RuvA with RuvC".

Step-by-step explanation:

RuvABC is a three proteins complex that is critical for DNA repair in bacteria. RuvAB is a helicase that is comprised of two of the tetramers of the complex that besides mediating branch migration, cleaves the Holliday intermediate by replacing one RuvA with RuvC. RuvAB perform its molecular activity by by localized denaturation and reannealing.
