It Needs A Template

a: Dna polymerase ~
b: a copy machine

What: "DNA polymerase cannot build "random" DNA molecules through the willy-nilly polymerization of nucleotides. It can only make copies of DNA molecules that already exist. Think of it this way -DNA polymerase is like a copy machine, NOT like a type writer, and a copy machine cannot print anything unless it has a template to work with."
