An important function of DNA is as a blueprint for proteins. This translation of DNA to a protein works in triples of DNA-letters. A triple of letters from DNA is referred to as a codon. DNA-sequences that encode proteins start with the start codon ATG and stops with one of the three stop codons TAA , TAG, or TGA. In between there is a number of complete codons. Figure out how to find the number of codons in tmp before the first stop codon.
