Adenine will only bond with Thymine, and Cytosine with only Guanine. The double helix is antiparallel, meaning each strand runs in a different direction. The first step to DNA replication is the unwinding of the double helix with the help of an enyme called helicase.Once unwound, the DNA unzips and the bonded nucleotides are separated. In the next stage, an enzyme called DNA polymerase is important.denine will only bond with Thymine, and Cytosine with only Guanine.
