WebHow 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 that the two strands are separated. DNA polymerase is responsible for matching the correct nucleotides on a newly made strand by using base-pairing. Web• We are focusing on these: •Helicase - separates DNA strands •DNA Polymerase - adds nucleotides and proofreads •Ligase- links new pieces of DNA DNA Replication 1. The enzyme helicase “unzips” or separates the two stands of DNA. 2. DNA polymeraseadds the nucleotides of the new strands using the old strand as a template. 3.

WebThe process of DNA replication is catalyzed by a type of enzyme called DNA polymerase ( poly meaning many, mer meaning pieces, and – ase meaning enzyme; so an enzyme that attaches many pieces of DNA). Observe … The main function of DNA polymerase is to synthesize DNA from deoxyribonucleotides, the building blocks of DNA. The DNA copies are created by the pairing of nucleotides to bases present on each strand of the original DNA molecule. This pairing always occurs in specific combinations, with cytosine along with guanine, and thymine along with adenine, forming two sepa…
