Scanning electron microscopy of isolated Chironomus polytene chromosomes.

Abstract

Individual polytene chromosomes have been isolated from Chironomus stigmaterus for scanning electron microscope observations. The three dimensional ultrastructure of these chromosomes consists of a series of chromatin strands extended in the interbands and more tightly coiled or folded in the banded regions. The nucleolus is observed to be a dense disc or doughnut shaped structure surrounding the chromosome while the Balbiani Rings appear as diffuse regions consisting of both fibrillar and granular elements.
