Question
The enzyme responsible for proofreading a growing DNA strand and for replacing mismatched nucleotides is: topoisomerase II. DNA ligase. DNA polymerase. helicase. DNA replicas. The lagging strand is the daughter strand that has its ______ end ported toward the replication fork and a therefore synthesized ______. 3'; in a series of segments None of the other answer options is correct. 5'; continuously 3'; continuously 5'; in a series of segments As a piece of linear DNA is replicated, the leading strand will have ______ RNA primer(s) and the lagging strand win have ______ RNA primer(s). many; many one; one one; many many; one one; two Which of the following enzymes is the FIRST to bind to the ONA sequences at the origin of replication? DNA helicase single-strand binding protein DNA ligase DNA polymerase DNA primaseExplanation / Answer
1. Dna polymerase
2. 3l in a series of segments. The series of segments is called okazaki segments
3. One, many. (leading strand replicated continuously by a single RNA primer and the lagging strand by many rna primers.
4. DNA helicase. This enzyme separates the double strands into single strands with the energy acquired from ATP.
