Popis: |
In nature, micro organisms experience numerous environmental stresses and generally grow poorly most of the time. In the last two decades it has become evident that mutations arise not only in actively dividing cells but also in non-replicating or slowly replicating cells starved for nutrients. In yeast, precise base selection and proofreading by replicative DNA polymerases δ and ε keep starvation-associated mutagenesis (SAM) at basal levels. Less is known about the role of replicative DNA polymerase α (Pol α). Here we provide evidence that Pol α is involved in the control of SAM in yeast cells starved for adenine by participation in sporadic replication and/or DNA repair under these conditions. |
