Aminoacyl-t RNA

Aminoacyl-t RNA

Aminoacyl-tRNA is tRNA (also known as transfer ribonucleic acid) to which its cognated amino acid is adhered. Its role is to deliver the amino acid to the ribosome where it will be incorporated into the polypeptide chain that is being produced. A specific amino acid is added to each tRNA, which is crucial since it means that only that particular amino acid will be incorporated when the anticodon of that tRNA fits (can form a transient base pair with) the next codon of the mRNA that is being translated into protein.

The specific linkage of the correct amino acid to each tRNA is accomplished by aminoacyl tRNA synthetases. Due to the degeneracy of the genetic code, some of the different tRNAs have the same amino acid attached to them.
