Which of the following best describes the function of the RecA protein in E. coli recombination?
A) Promotes strand invasion and formation of the D loop
B) Recognizes double-stranded breaks in the DNA
C) Is involved in the initial formation of the Holliday junctions
D) Resolves Holliday junctions into separate chromosomes

Question

Quizplus · Accepted Answer

The RecA protein promotes strand invasion and formation of the D loop in E. coli recombination by binding to single-stranded DNA and facilitating its invasion into a homologous double-stranded DNA molecule. This leads to the formation of a D loop, which can then be resolved to form a Holliday junction.
