DNA polymerase III
DNA polymerase III is a crucial enzyme in the process of DNA replication. It is responsible for synthesizing new DNA strands by adding nucleotides to a growing chain, using an existing DNA template. This enzyme ensures that the genetic information is accurately copied during cell division.
In prokaryotes, such as bacteria, DNA polymerase III is the primary enzyme involved in DNA replication. It works in conjunction with other proteins to form a complex known as the replisome, which coordinates the replication process. This enzyme has high fidelity, meaning it makes very few errors while copying DNA, which is essential for maintaining genetic stability.
