the data suggest that the decline in both dna excision repair-associated and mitogen-activated dna synthesis may be correlated with decreased total intracellular levels of dna polymerase and with the decline in polymerase alpha activity as a function of age , that dna repair-associated initiation of dna synthesis in adult-derived cells may increase with activation of a pool of low activity dna polymerase alpha , and that dna polymerase alpha activity increases as a function of enzyme interaction with a component of the pi phosphorylation cascade .
