A method of electing the presence or absence of exposed nuclear DNA is described. Cells are reacted with a reaction composition comprising DNA polymerase I, DNase I, and the nucleotides dATP, dCTP, dGTP, and dTTP or dUTP, at least one of said nucleotides being biotin labeled. Biotin labeled nucleotides incorporated in exposed DNA are detected. Also described is a kit useful for detecting the presence or absence of exposed DNA in cells.
