  1. True or False?
    Deoxynucleotides are made from the reduction of ribonucleoside monophostphates.
    • False.
    • They are made from the reduction of diphosphates.
  2. What enzyme catalyzes the reduction of ribonucleosides?
    Ribonucleotide Reductase.
  3. Identify what each of the following ribonucleosides are converted to following catalysis by ribonucleotide reductase: CDP, UDP, GDP, ADP.
    • 1.) dCDP
    • 2.) dUDP
    • 3.) dGDP
    • 4.) dADP
  4. How is Thymine synthesized for use in DNA?
    Thymidylate synthase converts dUMP to dTMP.
  5. What does thymidylate synthase do to dUMP to convert it to dTMP?
    It transfers a methyl-group from tetrahydrofolate (N5,N10 - mehtylenetetrahydrofolate) to the dUMP.
  6. Ribonucleotide reduc
