- How Is DNA Proofread? DNA polymerase is a handy little enzyme that helps with DNA replication and proofreads after it's done. During DNA replication, the DNA is "unzipped" so th…

- Proofreading During DNA Replication As you probably know, DNA is pretty important. So when a cell needs to make a copy of its DNA, it needs to be sure that there are no mistakes…
