Q What is the role of messenger the ribosomes and RNA for the protein synthesis?
The mRNA is produced within the cellular nucleus and migrates to the cytoplasm where associated to ribosomes it guides the building of amino acid sequences that will compose proteins. Ribosomes are sites for the binding and meeting of mRNA and transfer RNA (tRNA), they are the structures where amino acids transported by tRNA are united by peptide bonds forming polypeptide chains proteins.
