Chapter 11: DNA Replication and Recombination

  1. Holoenzyme matching exercise

  2. The helicase proteins break the ________ bonds between the bases that hold the double helix together.
    1. hydrogen
    2. covalent
    3. phosphodiester
    4. glycoside
    5. peptide
  3. Initiation of DNA synthesis requires a RNA primer made by the enzyme
    1. primase.
    2. ligase.
    3. helicase.
    4. gyrase.
    5. endonuclease.
  4. The discontinuous aspect of DNA replication in vivo is caused by
    1. polymerase slippage.
    2. trinucleotide repeats.
    3. the 5' to 3' activity of DNA polymerase.
    4. discontinuous action of helicase.
    5. sister-chromatid exchanges.
  5. Structures located at the ends of eukaryotic chromosomes are called
    1. centromeres.
    2. chromomeres.
    3. duplication mutations.
    4. telomeres.
    5. deletion mutations.
