The steps involved in DNA replication must happen in a precise order: Supercoiled double-stranded DNA is relaxed by an enzyme called topoisomerase (or gyrase) and then unwound by an enzyme called helicase, which opens up the two strands in one area at a time. Nucleotides matching the bases exposed by the unwinding base pair with their match. Displaying top 8 worksheets found for - Amoeba Sisters Video Recap Dna Replication Answer Key.
