ribonucleic acid, RNA - (biochemistry) a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes; it transmits genetic information from DNA to the cytoplasm and controls certain chemical processes in the cell; "ribonucleic acid is the genetic material of some viruses"

As a consequence, there are differences in frequency of different tRNA types for a given amino acid and, accordingly, they are variably available in a cell and the efficiency of translation by means of a given codon is also variable (Cannarozzi et al.
Synthesis begins with the formation of a 30S ribosomal subunit + charged tRNA + mRNA complex which recruits a 50S subunit to complete the mature 70S ribosome.
Of all the RNAs, tRNA exhibits the largest number and most diverse modifications with cells from all kingdoms of life allocating a large portion of their genome to encoding enzymes involved in the post-transcriptional modification of nucleosides in tRNA [1].
These posttranscriptional modifications are necessary for the structural integrity and decoding activity of tRNA (1-3).
Separately, a 3-chlorotyrosinecharged tRNA containing a CUs anticodon, was prepared by a combination of chemical synthesis and enzymatic ligation, followed by aminoacylation of 3-chlorotyrosine using an aminoacyl-tRNA synthetase (Fig.
So far, at least 20 types of mitochondrial mutations and 5 types of rearrangements have been detected to be relative with diabetes2, among which the A-to-G transfer in 3243 site of mitochondrial tRNA leucine gene is the most common.
Throughout the period of elongation, tRNA brings mRNA's corresponding amino acid from the cytoplasm to the ribosome.
