The diagram illustrates the stages involved in producing part of a polypeptide. DNA nucleotide sequence (template strand): $\text{TACGACAATCGC}$. mRNA sequence: $\text{AUGCUGUUAGCG}$. Amino acid sequence: met leu leu ala. Which feature of the triplet code is shown by the information provided?
- AAn amino acid can be coded for by more than one triplet.
- BThe triplet code is non-overlapping and is only read in one direction.
- CThe triplet code is universal for the DNA of all organisms.
- DThere are some triplets that code for ‘start’ and ‘stop’.
