Cells exposed to DNA damaging agents, produce different types of structural changes in the chromosome. Repair of these lesions requires synthesis of new DNA molecules, catalysed by specific DNA polymerases. A putative DNA polymerase has been characterized, for its role in DNA damage repair and radiation resistance in D. radiodurans, a bacterium best known for its extraordinary resistance to  ...
