DNSpolimerázokkal

DNSpolimerázokkal refers to DNA polymerases, which are enzymes crucial for DNA replication and repair in all known organisms. These enzymes are responsible for synthesizing new DNA strands from existing ones, a process that is fundamental to cell division and genetic inheritance. The core function of DNA polymerases is to add nucleotides to a growing DNA chain, using a template strand to ensure the accurate copying of genetic information. This synthesis always proceeds in a specific direction, from the 5' end to the 3' end of the new strand.

There are several different types of DNA polymerases within a single organism, each with specialized roles. For instance, in bacteria like *Escherichia coli*, DNA polymerase III is the primary enzyme for replication, while DNA polymerase I handles primer removal and DNA repair. Eukaryotes have an even more complex set of DNA polymerases, including polymerases alpha, delta, epsilon, and gamma, which are involved in nuclear DNA replication, mitochondrial DNA replication, and DNA repair. The process requires a primer, a short RNA or DNA sequence, to initiate synthesis. DNA polymerases also possess proofreading capabilities, allowing them to detect and correct errors made during replication, thereby maintaining the integrity of the genome. Mutations in DNA polymerases or their malfunction can lead to various genetic disorders and diseases, highlighting their essential role in cellular life.
