Enzymes that unwind dna
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. WebMay 23, 2024 · The enzyme DNA polymerase works only in the 5 to 3 direction. DNA polymerase can work continuously on the leading strand but works discontinuously on the lagging strand, creating Okazaki fragments. -is how this affect the leading strand and the lagging strand.
