Human dna polymerases
WebDNA polymerase is a type of enzyme that is helpful to make copies of the DNA in the form of Nucleic acid molecules. It is a group of enzymes required for the synthesis of DNA. It catalyses the synthesis of DNA during replication. Moreover, its main function is to duplicate the DNA and divide in cell division. Web20 Nov 2002 · Human DNA polymerase (Pol)κ is a member of the Y family of DNA polymerases. Unlike Polη, another member of this family, which carries out efficient translesion synthesis through various DNA lesions, the role of Polκ in lesion bypass has remained unclear.
