Each DNA molecule is in the form of a double helix (twisted ladder). To begin DNA replication, DNA Helicase must unwind the the two twisted strands of DNA by breaking the hydrogen bond formed between the nitrogen bases. This process is similar to unzipping a zipper. The point where DNA Helicase begins to unwind the two strands is known as the origin of replication.

- Helicase

When DNA helicase splits the two strands of DNA, they separate. The leading strand (left) is synthesized continuously, where as the lagging strand (right) is synthesized discontinuously. DNA Primase adds RNA primer and then DNA polymerase I takes RNA Primer and turns it into DNA. DNA Ligase forms phosphodiester bonds between the the old strands and their new compliments.
