ANSWER

Stabilize ssDNA and prevent reannealing or secondary structure formation. SSBs coat exposed single strands to maintain their accessibility and prevent unwanted structures during replication.

Practice questions

1 of 50Practice questions for this set
In a yeast model, a single gene knockout produces normal DNA synthesis rates but causes frequent small insertions and deletions specifically within short repeated sequences (e.g., AAAAAA). The phenotype is strongest after many rounds of cell division and is reduced when a second gene that promotes recombination is overexpressed. Based on the scenario, which outcome is most consistent with loss of the primary pathway that corrects small loops formed during copying of repetitive DNA?
