Answer:
E site will be empty as it is exit site for protein synthesis.
P site will have code AUA with three amino acids because it is the site for peptide synthesis.
A site will have UCC code with one amino acid because its the code for serine synthesis. Moreover, A site is binding site for charged t-RNA molecules during protein synthesis.
THE ACTIN has the active site to which the heads of the thick filament will bind.
The muscle is made up of two major protein fibers, which are the actin and the myosin. Muscle contractions occur when myosin and actin slide over each other in a series of repetitive events. The protein actin has a thin structure and is abundant in eukaryotic cells while myosin is a thick filament.
