No multistrandedness in mitotic chromosomes of Drosophila melanogaster.

Abstract

Feulgen cytophotometric measurements of neuroblasts in the first and third instar larvae of Drosophila melanogaster reveal the same DNA content for metaphases with chromosomes of different size. The total absorbance of all measured metaphases gives the four-fold value of that of the spermatids. Accordingly there seem to be no reasons to retain the assumption of a multistranded structure for the large chromosomes of metaphases in the third instar larvae.
