The function to be built, amino_acids, must return a list of a tuple and an integer when given a string of mRNA code.
def amino_acids(mrna):
protein = "" # Start with empty protein string
translation = {"AUG": "Met", "CCA": "Pro", "CCU": "Pro"} # Which codon translates for which amino acid
stop_codons = {"UGA"} # Define stop codons
while mrna: # Repeat loop while mRNA isn't exhausted
codon = mrna[:3] # Select first three codes
mrna = mrna[3:] # Remove current codon from mRNA
if codon in stop_codons:
break # Break loop if triple is a stop codon
amino_acid = translation[codon] # Translate codon into its amino acid
protein += amino_acid # Add the amino acid to the protein string
return protein
print(amino_acids("AUGCCACCUUGA"))
