Random Amplified Polymorphic DNA is molecular technique with unique advantage of utility in genetically isolated species without prior genomic information. The prime goal of the present study was to identify molecular characterization and understands the evolutionary advancement among five different vertebrate species. On the basis of the analysis of RAPD profiles amplified by six arbitrary primers that gave the best results in producing species-specific bands (OPG-04, OPG-12, OPG-13, OPG-16, OPG-17 and OPG19), the polymorphic bands were unique in 31.4%, 23.2%, 19.2%,11.3% and 10.8% of rats, avain, gecko, toads and murrels respectively. Based on results, dendrogram constructed for phylogenetic relationship shows wistar rats were most unique and distinct.
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.
