In DNA Replication, what is the function of Primase: works to connect discontinuous parts of DNA such as the nicks created by gyrase and the okazaki fragments Synthesizes RNA on a DNA template to provide an available 3'-OH group to continue with DNA synthesis O binds at the origin and begins to unwind the helix bind near the origin to maintain the complementary sequences of DNA from reforming the helical structure

What is the function of DNA polymerase? a. It degrades DNA in cells. b. It adds RNA nucleotides to a new strand. c. It coils DNA around histones to form chromosomes. d. It adds DNA nucleotides to a replicating strand. e. None of these.
Energy that drives the attachment of a nucleotide to the end of a growing strand of DNA comes from ________. a. the nucleotide b. DNA polymerase c. phosphate-group transfers from ATP
How does DNA replication occur in a precise manner to ensure that identical genetic information is put into the new chromatid? See Figures 8.12 and 8.13. FIGURE 8.12 In DNA replication, the two polynucleotide strands uncoil, and each is a template for synthesizing a new strand. A replicated DNA molecule contains one new strand and one old strand. This mechanism is called semiconservative replication. FIGURE 8.13 A close-up look at the process of DNA replication. (a) As the strands uncoil, bases are added to the newly synthesized strand by complementary base pairing with bases in the template strand. The new bases are linked together by DNA polymerase. (b) DNA synthesis can proceed only in the 5 3 direction; newly synthesized DNA on one template strand is made in short segments and linked together by the enzyme DNA ligase.
