Abstract excerpt
Tumor development is characterized by accumulation of mutations. Such mutations, if induced by carcinogens in DNA polymerase genes, would confer mutator properties on the DNA replication machinery, even at later stages of development. To investigate whether DNA polymerase delta can be mutated, we compared these enzymes from highly malignant Novikoff hepatoma cells and from regenerating normal rat liver. We...
