Repetitious DNA sequences have been isolated from a number of the primates in in both Suborders Anthropoidea and Prosimii by hydroxy-apatite chromatography at a Cot of 10. In addition to finding previously unreported possible AT-rich satellite DNAs in Orangutan, Gibbon, Rhesus and Slow Loris a clear similarity to human DNA was found in the nonsatellite repetitious DNA sequence properties of the primates in the Suborder Anthropoidea. This is based on the presence of the hydroxyapatitie isolated 1.703 and 1.714 g/cm3 DNA families in CsCl gradients in the analytical ultracentrifuge following renaturation and extensive DNA hyperpolymer network formation. Within the superfamily Hominoidea the amount of the 1.714 g/cm3 DNA family was greater than that of the 1.703 g/cm3 DNA family while the reverse situation was true within the Superfamily Cercopithecoidea. The orangutan 1.703 and 1.714 g/cm3 DNA families were shown to exhibit the same differential reassociation behavior demonstrated previously in human DNA (Marx et al., 1976a). These data are interpreted as preliminary evidence for a similar sequence organization in the Order Primates Suborder Anthropoidea.
