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 hold the DNA strands apart while they are being replicated. Primase is responsible for synthesizing RNA primers, ligase joins Okazaki fragments, DNA polymerase is responsible for adding nucleotides to the growing DNA strand, and exonuclease is responsible for removing nucleotides from a DNA strand. None of these directly hold the DNA strands apart.
