the final method uses a phosphatase-free dna polymerase preparation , 2'-damp to inhibit the 3 ' leads to 5 ' exonuclease of dna polymerase i , and includes a correction of both the background incorporation and the sample incorporation for dilution of the specific activity of the radioactive precursor by the sample .
