Rabbit globin mRNA has been purified and used as a template by reverse transcriptase. The resulting duplex molecule consisting of rabbit globin mRNA/cNDA has been linked in vitro to Eco RI cleaved plasmid Col E1 DNA. Transformation of E. coli C6OO by this recombinant molecule has been achieved. Transformed bacteria acquire the colicin EQ immunity of Col E1 and a closed circular DNA species of 4.40-4.45 x 10 (6) daltons in molecular weight, an increase of 2.0-2.5 x 10(5) daltons compared to that of the parent plasmid DNA. In addition , 3H cDNA synthesized from globin RNA hybridized perferentially to the recombinant plasmid DNA.
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.
