A memory effect in DNA replication.

PMID:  6375735     Owner:  NLM     Status:  MEDLINE    
A study of the polymerization/excision ratio in the replication of poly(dA), primed with oligo(dT), was carried out with E. coli DNA polymerase I, at various primer and enzyme concentrations. The variations in this ratio suggest that 1) the DNA polymerase is able to switch between two states of low and high exonuclease activities and 2) after dissociating from the template, the DNA polymerase drifts towards the low exonuclease state. The recovery of the high exonuclease state would require several successive incorporations.
