Peptide bond-A carbon-nitrogen chemical bond formed between amino acid subunits of a polypeptide chain. Peptidyl site-A three nucleotide position in a ribosome in which peptidyl tRNA is found. Peptidyl RNA-The name given to the tRNA located in the P site of the ribosome during translation.This tRNA holds the growing polypeptide chain. Peptidyl transferase-The enzyme responsible for catalyzing the peptide bond formation reaction between amino acids in the P site and A site of a ribosome during translation.his tRNA holds the growing polypeptide chain.

Ribosomes are the central structures of protein synthesis. They bring all the components needed to build a protein together in a controlled fashion that causes amino acids to link up in a chain. Ribosomes have sites that bind mRNA and tRNA and move them through the ribosome. The movement of RNA through the ribosome adds the amino acids to the chain, one at a time. Without ribosomes, the tRNA and the mRNA would have to spontaneously come together. After the association of the two kinds of RNA, the amino acids attached to the tRNA would have to link to together. Without a ribosome this would take a very long time. Ribosomes are the organizers of protein synthesis.
