The wild-type sequence of part of a protein is NH2-Trp-Trp-Trp-Met-Arg-Glu-Trp-Thr-Met Each mutant in the following table differs from wildtype by a single point mutation. Using this information, determine the mRNA sequence coding for the wild-type polypeptide. If there is more than one possible nucleotide, list all possibilities.
