Relationship between sporulation-specific 20S ribonucleic acid and ribosomal ribonucleic acid processing in Saccharomyces cerevisiae.
The nature and properties of the 20S ribonucleic acid which accumulates only during the sporulation of Saccharomyces cerevisiae were examined. The 20S ribonucleic acid (RNA) has a base composition considerably different from ribosomal RNA species and is virtually unmethylated. The 20S RNA did, however, exhibit approximately 70% homology with 18S RNA by RNA-deoxyribonucleic acid filter hybridiza...
متن کاملTranslation of satellite tobacco necrosis virus ribonucleic acid. II. Initiation of in vitro translation in procaryotic and eucaryotic systems.
This paper reports the N-terminal amino acid of the product of in vitro translation of satellite tobacco necrosis virus ribonucleic acid (STNV-RNA) by both a procaryotic (Escherichia coli) and eucaryotic (wheat embryo) system. In vitro translation of satellite tobacco necrosis virus RNA by the procaryotic (Escherichia coli) system initiates with fMet-tRNAyet. Specifically, deformylation of the ...
متن کاملImpact of microfluidic processing on bacterial ribonucleic acid expression.
Bacterial transcriptomics is widely used to investigate gene regulation, bacterial susceptibility to antibiotics, host-pathogen interactions, and pathogenesis. Transcriptomics is crucially dependent on suitable methods to isolate and detect bacterial RNA. Microfluidics offer ways of creating integrated point-of-care systems, analysing a sample from preparation, and RNA isolation to detection. A...
متن کاملRibonucleic acid metabolism in lymphocytes stimulated by phytohemagglutinin. II. Rapidly synthesized ribonucleic acid and te production of ribosomal ribonucleic acid.
Human peripheral lymphocytes are stimulated to change, in vitro, from a resting state to one of progressive enlargement, culminating in mitosis, by treatment with Phaseolus vulgaris phytohemagglutinin. The sedimentation characteristics and fate of rapidly synthesized RNA have been studied in this system after 20 hours of stimulation with phytohemagglutinin, a time when RNA synthesis has been ac...
متن کاملThe Enzymatic Methylation of Ribonucleic Acid and Deoxyribonucleic Acid. Vii. the Methylation of Ribonucleic Acid.
Preceding publications from this laboratory have shown that the methylation of soluble ribonucleic acid is catalyzed by at least six discrete enzymes (l-3) which have been purified from extracts of Escherichia coli W. Two of these enzyme preparations catalyze the formation of l-methylguanine residues in SRNA,1 while a third produces 7-methylguanine. The others catalyze the methylation of uracil...
