At 50°C, PCR primers are able to access target DNA before template strands can rejoin due to...A. ) Template being forced apart by single stranded binding protein Solution Correct answer is option A and B. Template being forced apart by single stranded binding proteins. Primers being more abundant than template. SsBP do not allow the dna strands to anneal until the primer attaches to the template strand. They help in more accurate PCR. Large number of primers means more chances of primers binding to target DNA..
