Two-dimensional polyacrylamide gel electrophoresis of tRNA [l] is becoming a remarkable
tool to investigate various problems dealing with the regulation of protein synthesis: accurate …

Using tRNA and aminoacyl-tRNA synthetase preparations from Drosophila melanogaster, a
method has been developed for simultaneously estimating levels of at least 15 different …

Abstract Six Drosophila melanogaster tRNA Tyr genes have been isolated and sequenced.
They contained introns of different sequences and two size classes: 20 or 21 base pairs …

Six purified tRNAs labeled with 125 I by chemical or enzymatic methods were hybridized to
polytene chromosomes of Drosophila melanogaster. The main chromosomal regions of …

Eighteen out of twenty amino acids have been used for identifying tRNAs from the silkworm
Bombyx mori L. fractionated on two-dimensional polyacrylamide gel electrophoresis. 43 …

Conditions for the chromatography of radioactively labeled Drosophila aminoacyl-tRNAs on
reversed-phase 5 columns have been established. All 20 aminoacyl-tRNAs from first instar …

We have previously reported that four tRNAs of Drosophila melanogaster randomly labeled
with iodine-125 hybridize in part to the 56EF region of polytene chromosomes where 5S …

Highly purified tRNAs from Drosophila melanogaster were iodinated with 125 I and
hybridized to squashes of polytene chromosomes of Drosophila salivary glands followed by …

A plasmid with the vector Col El attached to an insert of Drosophila melanogaster DNA
carrying four tRNA genes has been cloned in E. coli. Some features of the sequence …

Regulation of protein biosynthesis. at the translational level is believed to play an important
role in bringing about relatively rapid changes of cellular metabolism in e~ karyotes when …
