Chromatin diminution in Ascaris suum: nucleotide sequence of the eliminated satellite DNA.

RESUMO
We have determined the prototype sequence of the DNA which is eliminated in the course of chromatin diminution in Ascaris suum. This DNA which is virtually absent from somatic cells but retained in the germ line consists predominantly of highly repetitive sequences which are variants of an AT rich 123 base pair repeat unit. Both major and minor variants have been sequenced. The overall structure of this germ line limited DNA corresponds to the segmental organization characteristic of satellite DNAs. Possible correlations between the mechanism of chromatin diminution and some properties of the satellite sequence are discussed.
