One characteristic of DNA, CsCl buoyant density peak values, was determined for DNA samples isolated from 93 species belonging to 11 orders of mammals. The CsCl buoyant density values varied over a very narrow range, 1.696–1.701 g/cm3. Satellite DNAs were found in a number of species. The function and origin of these satellite DNAs are not known.
