title: Clustered GATA repeats (Bkm sequences) on the human Y chromosome.
abstract: Sixty eight individual clones of a human Y chromosome cosmid library were screened for the presence of GATA repeats, the major component of Bkm-related DNA sequences. Nine cosmid clones were found to cross-hybridize. The sequence organization of the repetitive base quadruplet GATA was analyzed using synthetic oligonucleotide probes. Subclones of GATA-positive cosmid clones were used for chromosomal localization of the Y-derived DNA sequences thus revealing male-specificity or male-female homology.
