Organization of DNA in dipteran polytene chromosomes as indicated by polarized fluorescence microscopy

J W MacInnes et al. Science. .

Abstract

Analysis of the polarization of fluorescence from Drosophila virilis polytene chromosomes stained with acridine orange suggests that the DNA in the interband regions of these chromosomes cannot be in a supercoiled configuration, but must lie parallel to the chromosome axis.
