Ribosomal RNA on the Surface of Ribosomes
Science, 1963Ribonuclease from pancreas releases nucleotide from Escherichia coli ribosomes while not altering significantly the base composition of the total ribosomal RNA. Ribonuclease hydrolyzes ribsomal RNA without destroying the structure of 70 S or 30 S and 50 S

Small Nucleolar RNAs Guide Ribosomal RNA Methylation
Science, 1996Two recent reports, one in Cell and one in the Journal of Molecular Biology , show that the newly described small nucleolar RNAs control the site of methylation of the ribosomal RNA (rRNA). Tollervey explains how these small RNAs accomplish this targeting and discusses the possible role of ...

1991
For a long time, cytochrome c, which is a slowly evolving protein, was the reference molecule to establish molecular phylogenies for very divergent eukaryotic lineages (Fitch and Margoliash 1967). Considering bacterial and chloroplastic c-type cytochomes together with cytochrome c, the first universal phylogenetic tree has been established. However, in
