Studies on transfer RNAs

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1972
Abstract 1. 1. Treatment of tRNA fMet with hydroxylamine caused specific modification of cytosine residues among a number of constituent nucleobases and only three out of the 26 cytosine residues in the tRNA were modified. The modified tRNA was found to charge methionine up to 64 % of its original acceptance. 2. 2.

Transfer RNA in reticulocyte maturation

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1981
The disappearance of tRNA during the maturation of rabbit reticulocytes under the stress of phenylhydrazine-induced hemolysis was studied. The tRNA content of reticulocytes and of erythrocytes derived from them was compared. The results show that tRNA persists longer after reticulocyte maturation than ribosomes and than the ability to incorporate amino

On the origin of the transfer RNA molecule

Journal of Theoretical Biology, 1992
Data and arguments are given in favour of the hypothesis that the primitive tRNA molecule may have originated from a direct duplication event involving one of the two halves of the tRNA molecule. It seems that a molecule capable of assuming a hairpin structure was involved as a precursor in this duplication.

Transfer RNA and Cytokinins

1977
When it was observed that soluble RNA (sRNA) played a vital role in protein synthesis, this low-molecular-weight species of RNA attracted much attention. The typical sRNA molecule, with a molecular weight of about 25,000 and a sedimentation constant of 4S, is a polynucleotide chain containing about 80 nucleotides.

Studies on transfer RNA and transfer RNA genes in Drosophila melanogaster

1977
In the present study Drosophila melanogaster was used to define the organization and expression of tRNA genes. The three major Drosophila valine tRNAs were isolated and purified by standard chromatographic techniques. Nucleoside analysis indicated that of these tRNAs only tRNA₄Val contained inosine.
