unusual facts about ribosomal



Acer nipponicum

A ribosomal DNA study of Acer species in 2006 placed A. nipponicum along with the related A.caudatum near the base of the phylogenetic trees recovered.

Archaellum

Archaea were first classified as a separate group of prokaryotes in 1977 by Carl Woese and George E. Fox based on the differences in the sequence of ribosomal RNA (16S rRNA) genes.

Asarum

Study of the internal transcribed spacer region (ITS) of nuclear ribosomal DNA, combined with morphological data, have yielded a better-resolved phylogenetic hypothesis, confirming the distinctiveness of the above-named genera.

Human Microbiome Project

The microbial genome data were extracted by identifying the bacterial specific ribosomal RNA, 16S rRNA.

Myriochelata

The evidence for this relationship between myriapods and cheilcerates derives from comparisons of nuclear ribosomal RNA genes, mitochondrial ribosomal RNA genes, and protein-coding genes.

Myxozoa

As their distinct nature became clear through 18S ribosomal DNA (rDNA) sequencing, they were relocated in the metazoa.

Nenad Ban

His interest in large macromolecular assemblies led him for his postdoctoral work to the Department of Molecular Biophysics and Biochemistry at Yale University where he determined the atomic structure of the large ribosomal subunit by X-ray crystallography, as part of the group in the laboratory of Thomas A. Steitz.

PRNA

NoRC associated RNA, a non-coding RNA element which regulates ribosomal RNA transcription

RPS4X

It has been suggested that haploinsufficiency of the ribosomal protein S4 genes plays a role in Turner syndrome; however, this hypothesis is controversial.

Small nucleolar RNA R12

snoR12 was identified by computational screen of the rice Oryza sativa genome and is predicted to acts as a methylation guide for 25S ribosomal RNA in plants.

Small nucleolar RNA R66

snoR66 was identified by a computational screening of the rice Oryza sativa genome and is proposed to acts as a methylation guide for 18S ribosomal RNA in plants.

Svedberg

For bacterial ribosomes, ultracentrifugation yields intact ribosomes (70S) as well as separated ribosomal subunits, the large subunit (50S) and the small subunit (30S).
