def source_rna (protein): This function takes in a string representing a sequence of proteins and returns the total number of different sjurce RNA strings, modulo 1,000,000. Essentially, you are calculating how many strands of mRNA from which this particular protein could have been translated. (HINT: You'll want to use/manipulate the codon table from rna codon ()! Example: Sample input protein string: "MA" The returned number of possible source RNA sequences: 12 def rna2codon(triplet): genetic_code = { UUU: 'F', 'UU': ' FUUA': 'L', 'UUG': 'L AU': 'I', 'Auc': 'I 'AUA: 'I'.
