Methylation process of mammalian ribosomal precursor RNA
Biochimie, 1976The analysis of RNA from L5178 Y cells, by electrophoreis in 1.7% polyacrylamide gel, after short time labelling with [methyl-3H] methionine, shows that the three molecular species 47S, 46S and 45S RNA from the ribosomal RNA "45S fraction" are methylated.

RNA editing of a miRNA precursor.
RNA (New York, N.Y.), 2004Micro RNAs comprise a large family of small, functional RNAs with important roles in the regulation of protein coding genes in animals and plants. Here we show that human and mouse miRNA22 precursor molecules are subject to posttranscriptional modification by A-to-I RNA editing in vivo.

RNA precursor molecules and ribonucleases in E. coli
Molecular and Cellular Biochemistry, 1973The post-transcriptional alteration of oneE. coli RNA species (tyrosine tRNA) by nucleases is now understood in some detail. Knowledge of this pathway has allowed us to speculate on the nature and control of the processing of otherE. coli RNA species by the combined attack of endo- and exo-nucleolytic ribonucleases. A review of the properties of knownE.

The molecular weights of yeast ribosomal precursor RNAs
Molecular Biology Reports, 1975The molecular weights of the predominant rRNA precursors as well as those of 26-S and 17-S mature rRNA from Saccharomyces carlsbergensis were determined by polyacrylamide gel electrophoresis in the presence of formamide. Mature 26-S + 5.8-S rRNA was found to have a molecular weight of 1.24 X 10(6) while their immediate precursor, 29-S RNA, had a ...

Isolation of ribosomal RNA precursors from lung
Analytical Biochemistry, 1977Abstract A method is presented for the isolation of ribosomal RNA precursors from lung. The very labile precursors of ribosomal RNA in mouse lungs can be isolated and preserved when lung tissue (i) is frozen in liquid nitrogen and pulverized, (ii) is homogenized in hypotonic buffer, (iii) nuclei are rapidly isolated after being sieved through ...

Nucleotide Sequence and Function of Transfer RNA and Precursor Transfer RNA
1973At present, we have to consider the functional interactions of the tRNA molecule without knowing its three-dimensional structure. Comparison of tRNA sequences has shown that they have a common hydrogen-bonded structure defined by the cloverleaf arrangement, and in addition they have certain common sequences or correlated sequences which may also be ...
