Evaluation of number average length analysis in quantifying double strand breaks in genomic DNAs.

Double strand breaks in DNA can be quantified down to very low frequencies (a few per Gigabase pair) in nanogram quantities of nonradioactive, genomic DNA by dispersing the DNAs on electrophoretic gels, digitizing them by quantitative electronic imaging, and calculating the DNA lengths by number average length analysis. No specific distribution of damages… CONTINUE READING
