Phylogeny of transfer RNA

Origins of Life, 1984
Phylogenetic trees of transfer RNA specific for phenylalanine, methionine initiator glycine and valine are constructed. Although the exact relationships between taxa cannot be obtained from the mere analysis of the sequences some conclusions can be drawn about the evolution of this molecule.

Evolution of transfer RNA

Journal of Molecular Biology, 1973
Abstract Evolution by gene duplication and subsequent divergence is indicated by similarities common to 43 different transfer RNAs. Pairwise comparisons of these tRNAs reveal additional similarity, greatest for certain pairs of tRNAs for the same amino acid in the same organism, and also occurring in certain pairs of tRNAs for different amino acids ...

Crystallization of Transfer RNA

Nature, 1968
A bacterial transfer RNA (tRNAFMet) has been obtained in micro-crystalline form. Its probable unit cell dimensions have been deduced from X-ray powder photographs.

Transfer RNA in RNA Tumor Viruses

1977
Publisher Summary This chapter reviews that the presence of the majority of the tRNAs inside an RNA tumor virus remains an enigma. The finding that specific tRNA molecules can serve as primers for DNA synthesis is of fundamental importance in the field of molecular biology.

Mitochondrial transfer RNAs in yeast: identification of isoaccepting transfer RNAs

Biochemistry, 1978
To delineate the total number of tRNAs encoded by yeast mitochondrial DNA (mtDNA), we have examined mitochondrial tRNA preparations for the presence of heterogenic isoaccepting tRNAs. Analyses of /sup 3/H-labeled aminoacylated mitochondrial tRNAs by reversed-phase column chromatography (RPC-5) coupled with hybridization to mtDNA detected only one major

Transfer RNA in Hepatomas

1978
1. Altered column-chromatographic profiles of a number of hepatoma and other tumor aminoacyl-tRNAs have been observed, most frequently for tRNAPhe, tRNAAsp, tRNAAsn, tRNATyr, tRNAHis, and tRNASer. 2. The chemical basis for the chromatographic alterations is still obscure, except that a tRNAPhe in Morris hepatoma 7777, which is not ...

GENETICS OF TRANSFER RNA

Annual Review of Genetics, 1972
Initially the only way of identifying tRNA genes was by DNA-RNA hy­ bridization. The discovery that informational suppression may result from muta­ tions in tRNA genes has not only allowed their genetic analysis but has led to the isolation of mutants important in understanding the function, structure, and synthesis of tRNA.

Selenium-Containing Transfer RNAs

1985
Publisher Summary One of the unique features of the amino acid transfer ribonucleic acids is their high content of modified nucleosides. Sulfur containing derivatives of uridine, adenosine, and cytidine are known in bacteria and in eukaryotic organisms. Specific incorporation of selenium into the tRNA of E.
