BIOD_152_Final_Exa m Correct Answer

What enzyme is responsible for relieving the stress associated with the twisting and untwisting of a DNA strand during replication. Topoisomerase As a replicated DNA strand elongates, what enzyme is responsible for adding nucleotides? DNA polymerase The energy required to add a nucleotide to a growing chain is supplied by an exergonic reaction involving the hydrolysis of the nucleotide's pyrophosphate tail (T/F) True During elongation, in which direction are new nucleotides being added to the leading strand? 5' — 3' The leading strand requires ____ # of RNA primers, and the lagging strand requires ____ # of RNA primers. One; more than one What replaces RNA nucleotides with DNA nucleotides in a newly synthesized strand? DNA Polymerase A class of DNA polymerase patrols newly added nucleotides and will remove nucleotides that are erroneous. How does the polymerase "know" a nucleotide is misplaced. Newly adde nucleotides are compared to th
