WebDNA helicase pries DNA strands apart, and DNA binding proteins hold onto them while DNA polymerase makes a copy. And yes, high heat inactivates most proteins—including most types of DNA polymerase. As for the DNA polymerase in PCR, its heat tolerance is unusual. It comes from a type of bacteria that lives in near-boiling hot springs. WebAug 17, 2024 · To amplify a segment of DNA using PCR, the sample is first heated so the DNA denatures, or separates into two pieces of single-stranded DNA. Next, an enzyme …
WebDNA polymerase III holoenzyme (Pol III HE) is an enzyme that catalyzes elongation of DNA chains during bacterial chromosomal DNA replication. Bacterial cells contain several distinct DNA polymerases. In Escherichia coli, five DNA polymerases have been found and designated as DNA polymerase I–V, in order of their discovery.
