Which of the Following Help(s)to Hold the DNA Strands Apart

Question

Which of the following help(s)to hold the DNA strands apart while they are being replicated?
A) primase
B) ligase
C) DNA polymerase
D) single-strand binding proteins
E) exonuclease

Accepted Answer

Single-strand binding proteins help to keep the DNA strands apart while they are being replicated. Primase is responsible for making RNA primers that DNA polymerase can add nucleotides to; ligase seals any gaps that may exist between Okazaki fragments during replication; DNA polymerase adds nucleotides to the growing DNA strand; and exonuclease helps to remove nucleotides from the DNA strand.
