Discuss the concept and consequences of built-in redundancy as it applies to amino acid sequences, and include an
example. What will be an ideal response?
ANSWER: Three nucleotides are needed to carry the information for one amino acid. However, some
amino acids can be specified by more than one combination of three nucleotides. For
example, glycine can be encoded from four different codons, with any of four different
nucleotides taking the final position in the triplet. This type of redundancy provides
flexibility and also decreases the probability of mistakes during triplet construction.
