DNA polymerase is the enzyme that synthesizes new DNA during DNA replication. DNA polymerase occasionally makes mistakes and adds the incorrect nucleotide. How is this mistake usually resolved? O The incorrect base pair is removed by non-homologous end-joining O The incorrect base pair is removed by nucleases O The incorrect base is usually left where it is to enhance genetic variation O The incorrect base is removed by the proofreading activity of DNA polymerase
What structural aspect of the DNA facilitates dissociation of the two DNA strands for replication? Covalent bonds between sugars and phosphate groups Purine-pyrimidine pairing 3' end phosphorylation O Antiparallel DNA strands O Hydrogen bonding between paired bases

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 O 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 O bind near the origin to maintain the complementary sequences of DNA from reforming the helical structure
X DNA gyrase helps replication by O O O O reducing the stress caused by the unwinding DNA. breaking the H bonds between complementary base pairs. combining nucleotides to the exposed strand providing energy to the helicase enzyme. preventing newly unwound DNA strands from hydrogen bonding.
A DNA polymerase has everything it needs for extension, EXCEPT for RNA primers. What is the most likely consequence of this? No DNA replication will occur at all O DNA replication will occur much more slowly O Replication will be highly error-prone O Only one DNA strand will be replicated
The replication of lagging strands of DNA differs from the replication of leading strands in that RNA primers are not required. O DNA ligase is not needed. primase is not required.. O DNA is replicated as short fragments.
Which of the following is correct about the function of DNA Ligase? DNA ligase is used on the leading strand and it joins any disconnected strand together O DNA ligase is used on the lagging strand which helps in joining fragments of the strand together O DNA ligase is used on the lagging strand and it aids in correcting mistakes on this specific strand O DNA ligase is used to maintain the replication fork structure
