Question

1. what is the function of the single - strand binding proteins (ssb) during dna replication? to break the hydrogen bonds holding the two dna strands together to bind temporarily to each strand of dna and keep them separated during replication to seal up the new nucleotides (okasaki fragments) into long continuous strands to add new nucleotides to each strand of dna

Explanation:

Single - Strand Binding Proteins (SSB) bind temporarily to each separated DNA strand during replication to prevent them from re - annealing and to protect them from nucleases. They do not break hydrogen bonds (that's helicase's job), seal Okazaki fragments (that's DNA ligase's job), or add new nucleotides (that's DNA polymerase's job).

Answer:

to bind temporarily to each strand of DNA and keep them separated during replication
