<P> In protein synthesis , a succession of tRNA molecules charged with appropriate amino acids are brought together with an mRNA molecule and matched up by base - pairing through the anti-codons of the tRNA with successive codons of the mRNA . The amino acids are then linked together to extend the growing protein chain , and the tRNAs , no longer carrying amino acids , are released . This whole complex of processes is carried out by the ribosome , formed of two main chains of RNA , called ribosomal RNA ( rRNA ) , and more than 50 different proteins . The ribosome latches onto the end of an mRNA molecule and moves along it , capturing loaded tRNA molecules and joining together their amino acids to form a new protein chain . </P>
