DNA replication is the process of copying a double-stranded DNA molecule to produce two identical copies. It's an essential process for cell division, as the new daughter cells must contain the same DNA as the parent cell. 



Here are some things to know about DNA replication: 



Origin of replication

DNA replication begins at a specific region called the origin of replication. 


Replication fork

The replication fork is the area where DNA replication takes place. 


Helicase

Helicase is an enzyme that unwinds the DNA double helix and separates the hydrogen bonds between the two strands. 


DNA polymerase

DNA polymerase is an enzyme that creates DNA molecules by assembling nucleotides. DNA polymerase III is the primary enzyme involved in DNA replication. 
DNA ligase

DNA ligase is an enzyme that helps correct breaks in the DNA backbone structure. It plays an essential role in DNA replication, repair, and recombination.
