(1) Thus, the different tRNA-modification enzymes vary considerably in their sensitivity to perturbations of the tertiary structure of their tRNA substrates.

(2) Transfer RNA ( tRNA ) A type of RNA that participates in protein synthesis in living cells.

(3) Amino acids combined in tRNA complexes may be regarded as sequestered, or compartmented.

(4) Like mRNA, both tRNA and rRNA are transcripts of chromosomal DNA.

(5) As translation starts, a tRNA molecule binds to it and delivers the correct amino acid.

(6) The secondary structures for valinespecific tRNA - like structure generally display striking similarity to those of eukaryotic tRNA ~ ( val ) .

(7) The immediate transcript of a t RNA gene is known as precursor tRNA.

(8) As the protein grows, additional amino acids are brought into place by the correct tRNA molecules.
