WebAs DNA replication continues and the replication bubble expands, the parental double helix is unwound and separated into its two component strands. This unwinding and separating of the DNA requires three different types of proteins: helicase, topoisomerase, and single-strand binding proteins. 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’.
