(1) mRNA carrying codons which encode sequence in
which amino acids should be joined.
(2) tRNA which carry specific amino acids at one end
and an anticodon at the other.
(3) Ribosome which is the organelle that facilitates the
linkage of anti-codons to codons and also facilitates
peptide bond formation. They act as enzymes
controlling the process of protein synthesis.
2. tRNA with specific amino acids (Met and Leu)
