DNA replication occurs during the synthesis (S) phase of the cell cycle, before a cell divides. Enzyme brings in complementary N-bases B. Fully Editable Teacher Edition. Prepare DNA for complementary base pairing. DNA replication: ¥Complementary base pairing produces semiconservative replication ÐDouble helix unwinds ÐEach strand acts as template ÐComplementary base pairing ensures that T signals addition of A on new strand, and G signals addition of C ÐTwo daughter helices produced after replication. Helix unwinds and 2 DNA strands separate at the Hydrogen bonds between nitrogen bases. In conservative replication, the parental DNA remains together, and the newly formed daughter strands are together. Helicase opens up the DNA double helix, resulting in the formation of the replication fork. DNA and Replication Notes pdf: File Size: 236 kb: File Type: pdf: Download File.

They unzip like a zipper using DNA Helicase (enzyme) Each strand then builds its opposite strand by base pairing with nucleotides that float freely in the nucleus. Report a problem. DNA is replicated during theS (synthesis) stage of thecell cycle. Replication copies the genetic information. Thus DNA replication is a form of semi-conservative replication because each DNA has one strand belonging to the parent and one new strand. The 2 nucleotide strands separate at base pairs.
