Abstract:The maturation of 5S ribosomal ribonucleic acid (rRNA) in the obligately photoautotrophic unicellular blue-green alga Anacystis nidulans has been studied by using polyacrylamide gel electrophoresis and Ti ribonuclease oligonucleotide analysis. A. nidulans mature 5S rRNA (m5) is of approximately the same molecular weight as the 5S rRNA of Escherichia coli, and is derived by cleavage of a precursor (p5) containing a few (three to six) additional nucleotides. Some of these additional nucleotides occur at the 5' e… 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.
