"WebAfter Watson and Crick proposed the double helix model of DNA, three models for DNA replication were proposed: conservative, semiconservative and dispersive. But Meselson and Stahl proved semiconservative is actual the mode of DNA replication .

WebSection Summary. During cell division, each daughter cell receives a copy of each molecule of DNA by a process known as DNA replication. The single chromosome of a prokaryote or each chromosome of a eukaryote consists of a single continuous double helix.

WebJul 21, 2024 · The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA molecule.; This is carried out by an enzyme called helicase which breaks the hydrogen bonds holding the complementary bases of DNA together (A with T, C with G).; The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’.
