1.	Question : There is only one possible sequence of amino acids when deduced from a given nucleotides. But multiple nucleotide sequences can be deduced from a single amino acid sequence. Explain this phenomenon.
Answer» Solution : Some AMINO acids are CODED by more than one codon (known as degeneracy of codons), hence on deducing a NUCLEOTIDE sequence from an amino acid sequence, multiple nucleotide sequence will be obtained. For e.g., Ile has three codons: AUU, AUC AUA hence a DIPEPTIDE Met-Ile can have the following nucleotide sequence : (i) AUG - AUU (ii) AUG - AUC (III) AUG - AUA If we deduce amino acid sequence for the above nucleotide sequences, all the three will code forMet-Iie
