  • What does DNA polymerase do during DNA replication?
    DNA polymerase synthesizes new DNA strands by adding nucleotides to a growing DNA chain, extending from the 5' to 3' direction.
  • What enzyme places the nucleotides on the DNA strand during replication?
    DNA polymerase is responsible for placing nucleotides on the DNA strand during replication.
  • What is the function of DNA polymerase in DNA replication?
    The function of DNA polymerase in DNA replication is to synthesize new DNA strands by adding nucleotides to the template strand.
  • What is the role of DNA polymerase in the DNA replication process?
    DNA polymerase's role in DNA replication is to elongate the new DNA strand by adding nucleotides in the 5' to 3' direction.
  • What enzyme glues the nucleotides together along the sugar-phosphate backbone?
    DNA ligase is the enzyme that glues the nucleotides together along the sugar-phosphate backbone.
  • What is the role of DNA ligase in the elongation of the lagging strand during DNA replication?
    DNA ligase joins Okazaki fragments on the lagging strand, forming a continuous DNA strand.
