[32P]tRNA from baker's yeast is incorporated without degradation into lympholeukotic cells of L1210 mice. The tRNA incorporation determined after tRNA hydrolysis on cell surface by RNAase increases linearly with a rise in the initial concentration from 0.5 to 500 micrograms per ml. According to gel electrophoresis of intracellular nucleic acids, after a 3 hour incubation the [32P]tRNA incorporated into the cells by 50% to form tRNA fragments without any conspicuous reutilization. The kinetic curve of tRNA incorporation during the first 60 min demonstrates a severalfold decrease in the initial maximal incorporation of [32P]tRNA into the cells (2 min), with a subsequent restoration of the incorporation within 2-3 hours.

D012343 RNA, Transfer The small RNA molecules, 73-80 nucleotides long, that function during translation (TRANSLATION, GENETIC) to align AMINO ACIDS at the RIBOSOMES in a sequence determined by the mRNA (RNA, MESSENGER). There are about 30 different transfer RNAs. Each recognizes a specific CODON set on the mRNA through its own ANTICODON and as aminoacyl tRNAs (RNA, TRANSFER, AMINO ACYL), each carries a specific amino acid to the ribosome to add to the elongating peptide chains.
