Answer:
Formation of amino-acid building blocks.
Explanation:
Protein is one of the most important biomolecule present in the living organisms. Enzymes, antibodies, clotting factors and different peptides are made of protein.
The proteins are made of the polymer of the amino acids that are linked together by the peptide bond. The first step in the formation of the protein is the amino acid building block formation in the cell and later the proper folding of the polypeptide.
Thus, the answer is formation of amino-acid building blocks.
