Linking ezyme which catalyzes the covalent bonding of one DNA fragment to another

Enlongates new DNA by adding nucleotides to the 3' end of an existing chain

Untwists the DNA double helix, making each side an availible template

Cuts DNA or RNA, breaking it down into its component nucleotides

Uses the parental DNA as a template to build an RNA primer

Helps relive strain in the double helix ahead of the replication fork
