Repeated nucleotide sequences in human main band DNA.
Male and female human placenta DNA was fractionated in an Ag+-Cs2SO4 density gradient. The different fractions along the gradient were analyzed by Hae III endonuclease digestion. Within the main band DNA on the light side a component having a Hae III digestion pattern similar to that of human satellite III DNA has been identified. This component which might be defined as a cryptic satellite accounts for at least 3% of the total human DNA and has a different position than human satellite III in Ag+-Cs2SO4.
