DNA replication begins at origins of replication where the helicase enzyme unwinds and unzips the DNA into two strands. The DNA polymerase enzyme then builds a new complementary strand to each single DNA strand, using the existing strand as a template to create an identical copy.

2. REPLICATION PROCESS
DNA starts its replication at origins of replication. The helicase then unzips
the DNA into to different sides. Then a new side to each part of the DNA
starts building itself.
