DNA polymerase. Computer model of a molecule of DNA polymerase replicating a strand of DNA (deoxyribonucleic acid, across centre). The secondary structure of the DNA polymerase and the primary structure of the DNA molecule are shown. DNA polymerases are enzymes that synthesise new strands of DNA from a complementary template strand during DNA replication. This molecule belongs to the Y family of DNA polymerases, which are translesion synthesis polymerases, that is they are able to replicate damaged areas of DNA that stall other DNA polymerases. The replication is not always accurate and can lead to mutagenesis or cancer.
