Which of the following help(s) to hold the DNA strands apart while they are being replicated?

Question

Quizplus · Accepted Answer

Single-strand DNA binding proteins (SSB proteins) help to hold the DNA strands apart while they are being replicated. They bind to and stabilize single-stranded DNA, preventing it from re-forming base pairs with the complementary strand. This allows the replication machinery to access and copy the individual strands. Primase (A) is an enzyme that synthesizes short RNA primers that are necessary for DNA polymerase to initiate replication. Ligase (B) is an enzyme that catalyzes the joining of DNA fragments, and is not involved in holding the strands apart during replication. DNA polymerase (C) is the enzyme responsible for synthesizing new strands of DNA and proofreading them for errors, but it does not directly hold the strands apart. Nuclease (E) is an enzyme that breaks down nucleic acids, and is not involved in DNA replication.
