Enzymes that unwind dna
WebThe enzymes responsible for adding nucleotides to the exposed DNA bases during replication are a. replicases b. DNA polymerases c. helicases d. template enzymes: … WebO Enzymes unwind the DNA, cut out a section on one stand that contains the DNA damage, and resynthesize the section with the correct DNA sequence. Enzymes delete an incorrect DNA sequence, pull the gap closed, and join the bases on either side of the gap together. Enzymes identify a mismatched base in a DNA strand, remove the incorrect …

WebMay 29, 2024 · The Enzyme named helicase unwinds the double helix model of DNA. It helps in unwinding of the DNA by breaking the hydrogen bonds in between them. It starts from the origin of replication and forms a replication fork by separating the two strands.These two separated strands are known as the parental strands. WebWhile Helicase works to unwind the DNA molecule, Ligase is the replication enzyme that binds the fragments together by addition of phosphates in the gaps that remain in the phophate-ribose sugar …
WebJun 12, 2010 · To 'unwind' the double helix for protein synthesis, enzymes called DNA Helicases cause the two parent DNA strands to unwind and separate from one another in both directions.
