WebOct 7, 2024 · Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands. DNA has four bases called … WebThe 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’.

In a double helix structure, the strands of DNA run antiparallel, meaning the 5’ end of one DNA strand is parallel with the 3’ end of the other DNA strand.
