The five satellite DNAs of Drosophila melanogaster have been isolated by the combined use of different equilibrium density gradients and hydrolyzed by seven different restriction enzymes; Hae III, Hind II + Hind III, Hinf, Hpa II, EcoR I and EcoR II. The 1.705 satellite is not hydrolyzed by any of the enzymes tested. Hae III is the only restriction enzyme that cuts the 1.672 and 1.686 satellites. The cleavage products from either of these reactions has a heterogeneous size distribution. Part of the 1.688 satellite is cut by Hae III and by Hinf into three discrete fragments with M.W. that are multiples of 2.3 X 10(5) daltons (approximately 350 base pairs). In addition, two minor bands are detected in the 1.688-Hinf products. The mole ratios of the trimer, dimer and monomer are: 1:6.30 : 63.6 for 1.688-Hae III and 1 : 22.0 : 403 for 1.688-Hinf. Circular mitochondrial DNA (rho = 1.680) is cut into discrete fragments by all of the enzymes tested and molecular weights of these fragments have been determined.
