During DNA replication (copying), most DNA polymerases can “check their work” with each base that they add. This process is called proofreading.

WebJan 16, 2024 · DNA Replication is a very unique and complex multistep biological process of producing two identical replicas from one original DNA molecule. It occurs in all living organisms (both prokaryotes and eukaryotes) because it forms an essential part of biological inheritance. It requires a number of enzymes, protein factors, and metal ions. WebApr 14, 2024 · DNA replication introduces a gradient of gene copy numbers, and in Bacteria it affects gene expression accordingly.
