Question 32

A synthetic mRNA molecule has the following base sequence:

5’ - AUG CAG GUC UAA CCG GAU - 3’ \text{5' - AUG CAG GUC UAA CCG GAU - 3'} 5’ - AUG CAG GUC UAA CCG GAU - 3’

During translation, polypeptide synthesis starts at the first codon (AUG) and stops when a stop codon (UAA) is reached. How many peptide bonds are present in the completed, translated polypeptide chain?
