What is the role of single-stranded DNA binding proteins (SSBs) during replication?
Show answer and explanation
Correct answer: They prevent re-annealing of unwound parental strands
SSBs coat the separated single strands at the replication fork, preventing them from re-forming a double helix or forming secondary structures, thus enabling polymerases to access the templates.
