Question

Template theory suggests

• A. Amino acids have to be activated
• B. Acylation
• C. Combination of amino acid with tRNA first
• D. All of the above

Answer 1

Answer: (D)

All of the above

Template theory suggests that proteins are synthesized on templates; there is one template for each protein, the genes. Transfer RNA serves to transport the monomers to the template; statement C is correct. The theory suggests that there is activation of amino acids before their incorporation into polypeptides; statement A is correct. The post-translational modification of the completed polypeptide, acylation of N-terminal, ensures fidelity of translation and the proper function of the protein product; statement B is correct. The correct answer is D.
