SYNOPSIS. Deoxyribonucleic acids (DNAs) isolated from 12 representatives of cellular slime molds grown in monoxenic cultures were analyzed by density gradient centrifugation in CsC1. The unique contribution of the DNA of each food organism was subtracted and the DNA base composition of each cellular slime mold determined. The guanine plus cytosine contents range 22–37 moles % within the representatives of the order. Minor bands (satellite bands) of DNA have been observed in preparations from Dictyostelium spp. and from Polysphondylium pallidum.
