It is found in the ribosomes with an enzymatic activity that catalyzes the formation of a covalent peptide bond between the adjacent amino acids. Peptidyl transferase is the main enzyme used in Translation.The polypeptide chain keeps growing until it reaches a stop codon. rRNA then helps to form bonds between the amino acids as they are transported to the ribosomes one by one, thus creating a polypeptide chain. When tRNA is bound to mRNA, the tRNA then releases its amino acid.For example Lysine is coded by AAG, and therefore the anticodon that will be carried by tRNA will be UUC, therefore when the codon AAG appears, an anticodon UUC of tRNA will bind to it temporarily. Each tRNA has an anticodon for the amino acid codon it carries which are complementary to each other.The ribosomes have two subunits of rRNA and proteins, a large subunit with three active sites (E, P, A) which are critical for the catalytic activity of ribosomes.the rRNA has the peptidyl transferase activity that bonds the amino acids.
The translation process is aided by two major factors: A translator – this is the molecule that conducts the translation substrate – this is where the mRNA is translated into a new protein (translator desk).
