DNA replication steps

1

 DNA replication happens in the synthesis

 DNA replication begins at an origin of replication steps. 

2

DNA helicase begins to separate the hydrogen bonds while topoisomerase begins to help unwind the strands. 

3

DNA primase - primers is the original DNA strand to allow new nucleotides in the DNA.

4

Polymers work from 5’ to 3’ IT creates a side that joins free floating DNA quickly.

5

The leading strand continuous to work forward as it replicates.

6

The lagging strand is more complicated, small sections are made called Okazaki fragments which join together.

7

DNA ligase bonds together the unjointed sections of newly made strands.

Why is it necessary or important?

DNA replication happens/necessary so each new cell gets the same set of instructions as the original cell.
