There is only one possible sequence of amino acids when deduced from a given nucleotide sequence. However,multiple nucleotide sequences can be deduced from a single amino acid sequence. Explain this phenomenon.

(N/A) The genetic code is degenerate,meaning that some amino acids are encoded by more than one codon. Because of this degeneracy,a single amino acid sequence can correspond to multiple possible nucleotide sequences.
For example,the amino acid Isoleucine (Ile) is coded by three codons: $AUU$,$AUC$,and $AUA$. Therefore,for a dipeptide like Met-Ile,the possible nucleotide sequences include: $(i)$ $AUG-AUU$,$(ii)$ $AUG-AUC$,and $(iii)$ $AUG-AUA$. Conversely,if we deduce the amino acid sequence from any of these three nucleotide sequences,all will code for the same dipeptide,Met-Ile.
