Question

Quizplus · Accepted Answer

The RecA protein in E.coli promotes strand invasion and D-loop formation in the double-stranded break model of DNA repair. This protein helps to initiate the process of homologous recombination, which is important for repairing broken or damaged DNA strands. RecA binds to single-stranded DNA at sites of damage and searches for a complementary strand of DNA to invade and initiate repair. This process ultimately leads to the exchange of genetic information between the damaged DNA strand and a homologous intact DNA strand, resulting in the repair of the damaged DNA.
