14. DNA Synthesis

The role of DNA polymerases in DNA replication is to __________.

Unlike prokaryotic DNA replication, replication of eukaryotic chromosomes __________.

Which of the following is not a property of DNA polymerase? a. It adds dNTPs only in the 5'→3' direction. b. It requires a primer to begin synthesis. c. It opens the two strands of DNA at the replication fork. d. Its exonuclease activity is involved in proofreading.

What is the function of primase? a. synthesis of the repetitive, short double-stranded DNA sequences required by DNA polymerase b. synthesis of a short RNA strand that is complementary to single-stranded DNA c. closing the gap at the 3′ end of DNA after excision repair d. removing primers and synthesizing a short section of DNA to replace them

DNA polymerase                   . a. attaches sister chromatids at the centromere; b. synthesizes daughter DNA molecules from fats and phospholipids; c. is the enzyme that facilitates DNA synthesis; d. causes cancer cells to stop dividing
