Restriction enzymes induced bands in the cave cricketDolichopoda schiavazzii(Orthoptera, Rhaphidophoridae): Implications for heterochromatin characterization and satellite DNA distribution
Abstract:In this study the activity of some class II restriction endonucleases, RE, on fixed metaphase chromosomes has been tested on two sample populations of the cave cricket Dolichopoda schiavazzii, a species endemic in Tuscany. In particular, the 6-base cutter PstI was chosen to detect the occurrence and localization on chromosomes of a satellite DNA family (named pDoP102) whose repetition units, analyzed in a previous study, contain the cleavage site of this enzyme. A comparison of the PstI digestion pattern and t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
