PMID:  7297244     Owner:  NLM     Status:  MEDLINE    
The lampbrush loops of the Y chromosome in primary spermatocytes of Drosophila hydei can be stained in a site specific manner employing a modified Giemsa technique. In this communication it is shown that pronase pretreatment changes the staining properties of the various Y loops as well as of the X and autosomes. In addition it is shown that the various chromosomal structures display differences in sensitivity against the action of the enzyme supporting the idea of a site specificity of RNP formation.
