Questions and Answers

What is the primary function of the enzyme DNA Ligase in DNA replication?

  • Unwinds the DNA double helix
  • Adds phosphate to the phosphate-sugar backbone (correct)
  • Adds complementary nucleotides to the DNA strand
  • Attaches RNA primers to the replicating strands

    • What is the purpose of the telomeres at the ends of DNA strands?

  • They are removed in every cycle of replication (correct)
  • They inhibit the action of DNA Polymerase
  • They contain coding DNA for protein synthesis
  • They are the starting points for DNA replication

    • What is the role of RNA Primase in DNA replication?

  • To attach RNA primers to the replicating strands (correct)
  • To add phosphate to the phosphate-sugar backbone
  • To synthesize new DNA strands
  • To unwind the DNA double helix

    • What is the process called when the DNA Polymerase reaches the end of the strands?
