Questions and Answers

In the process of DNA replication, which of the following statements is true?

  • Both strands of the double helix are completely newly synthesized.
  • One strand of the double helix is conserved from the parent molecule, and the other is newly synthesized. (correct)
  • Both strands of the double helix are conserved from the parent molecule.
  • The process involves the synthesis of a completely new double helix, independent of the parent molecule.

    • In the process of DNA synthesis, which end of the growing polynucleotide chain do nucleotides get added to?

  • Both the 5' and 3' ends simultaneously
  • The 5' end
  • The ends are not relevant; nucleotides can be added anywhere along the chain.
  • The 3' end (correct)

    • What is the role of the template strand during DNA synthesis?

  • It is responsible for unwinding the double helix during replication.
  • It serves as a primer for initiating DNA synthesis.
  • It provides instructions for the order of nucleotides to be added via base pairing. (correct)
  • It acts as a catalyst for the addition of nucleotides.

    • What is required for a phosphodiester bond to form between nucleotides during DNA synthesis?
