The coat protein of tomato bushy stunt virus consists of 180 chemically identical subunits, each of which is composed of 386 amino acid residues. the probability that a wrong amino acid residue will be biosynthetically incorporated in a polypeptide chain is 1 part in 3000 per residue. calculate the average number of coat protein subunits that would have to be synthesized in order to produce a perfect viral coat. what would this number be if the viral coat were a single polypeptide chain with the same number of residues that it actually has?
