Location and underreplication of satellite DNA in Drosophila melanogaster.

P Wollenzien, P Barsanti, J E Hearst.   

Abstract

The two light nuclear satellites (PCsC1 = 1.672 and PCsC1 = 1.687) have been quantified in DNA isolated from the larvel imaginal discs and brains of Drosophila melanogaster with the genotypes X/O, X/X and X/Y. By comparing the results from these different genotypes, the amounts of the two satellites in the X and Y chromosomes and in the autosomes have been determined. The lightest satellite is not located to any appreciable extent in the X chromosome. The heterochromatic regions are not completely filled by these satellites. --Satellite DNA has also been quantified in DNA isolated from adults containing different genotypes. The two satellites are underreplicated to different extents. The apparent amount of underreplication for one of the satellites is different in different parts of the genome.
