DNA replication of Eukaryotes (cells with a nucleus) occurs stepwise. Each step needs different enzymes. The DNA replication steps can be broken down as: A notch is made by DNA gyrase. This looks like a bubble under a microscope, called Replication Bubble. Cracking up the hydrogen bonds in the double helix is the vital step and it occurs where more A-T bases exist.
