  • What is the role of DNA polymerase in DNA proofreading?

    DNA polymerase has a proofreading ability that finds and fixes errors during DNA replication, reducing the error rate to 1 in 10,000,000,000 base pairs.

  • How do DNA repair enzymes complement the proofreading function of DNA polymerase?

    DNA repair enzymes correct errors that DNA polymerase proofreading might miss, further reducing the likelihood of mutations.

  • What is the significance of the error rate reduction from 1 in 100,000 to 1 in 10,000,000,000 base pairs?

    This significant reduction in error rate makes mutations due to DNA replication errors much less likely.

  • what process repairs damage to a preexisting double helix? see concept 16.2 (page)
    The process that repairs damage to a preexisting double helix involves DNA repair mechanisms, including the proofreading ability of DNA polymerases and other DNA repair enzymes. DNA polymerases can identify and correct errors during DNA replication, significantly reducing the error rate. Additional repair enzymes further correct any remaining errors, maintaining genetic integrity and preventing harmful mutations.
