Noun
RNA molecules present in the cell (in at least 20 varieties, each variety capable of combining with a specific amino acid) that attach the correct amino acid to the protein chain that is being synthesized at the ribosome of the cell (according to directions coded in the mRNA)

Aminoacyl transferase binds AMP-amino acid to tRNA. Source: Internet
Each ribosome is divided into two subunits: 1. a smaller subunit which binds to a larger subunit and the mRNA pattern, and 2. a larger subunit which binds to the tRNA, the amino acids, and the smaller subunit. Source: Internet
Amino acids are selected, collected, and carried to the ribosome by transfer RNA (tRNA) molecules, which enter one part of the ribosome and bind to the messenger RNA chain. Source: Internet
It was found to be a circular DNA molecule 4.6 million base pairs in length, containing 4288 annotated protein-coding genes (organized into 2584 operons ), seven ribosomal RNA (rRNA) operons, and 86 transfer RNA (tRNA) genes. Source: Internet
In between a grouping of five tRNA genes, a sequence resembling vertebrate origin of light strand replication is found. Source: Internet
