Human Y-chromosome-specific reiterated DNA

Human Y-chromosome-specific reiterated DNA

L M Kunkel et al. Science. .

Abstract

Radiolabeled reiterated DNA specific for the human Y chromosome has been obtained by extensive reassociations between [3H]DNA prepared from men and excess DNA from women. These highly purifed labeled sequences reassociate only with DNA from individuals with a Y chromosome. The percentage of Y-chromosome-specific DNA isolated from individuals with differing numbers of Y chromosomes is a function of the number of chromosomes present. The purifed Y-chromosome-specific sequences may represent between 7 and 11 percent of the human Y chromosome.
