Electron Microscopic Analysis of Chromosome Metabolism in the Drosophila melanogaster Embryo

This is the authors' abstract. We don't add key points for this paper.

Information regarding the patterns of chromatin transcription and replication is important in understanding the mechanisms regulating genome metabolism. Electron microscopic procedures provide a useful tool for the study of chromosome function. We have chosen to apply the technique of chromatin spreading to Drosophila melanogaster as it is a well-studied biological system that is amenable to cytogenetic manipulation.
