1.	Question : There is only one possible sequence of amino acids when deduced from a given nucleotides. But multiple nucleotides sequence can be deduced from a single amino acid sequence. Explain this phenomena.
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 EXAMPLE, lie has three codons : AUU, AUC AUA hence a depeptide. Met-lle can have the following nucleotide sequence: (i) AUG-AUU (ii) AUG-AUC (iii) AUG-AUA - And if, we deduce amino acid sequence the above nucleotide sequences, all the three will code for Met-lle
