Question

Quizplus · Accepted Answer

Single-stranded binding proteins keep the two strands of DNA separated by binding to single-stranded regions of DNA and preventing the two parental strands from reannealing. This allows other replication enzymes, such as DNA polymerase, to access the template strand and synthesize a new complementary strand.
