1.Helices In DNA Replication Function & Model
DNA helicase is the enzyme that unwinds the DNA double helix by breaking the hydrogen bonds down the center of the strand. It begins at a site called the origin of replication , and it creates a replication fork by separating the two sides of the parental DNA. 9 Jan 2022
