There is only one possible sequence of a | Class 12 Biology Chapter Molecular Basis of Inheritance, Molecular Basis of Inheritance NCERT Solutions

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:

Some amino acids are coded by more than one codon which is known as degeneracy of codons. Hence, on deducing a nucleotide sequence from an amino acid sequence, multiples nucleotide sequence will be obtained, example; Ile (isoleucine) has three codons AUU, AUC, AUA. Hence, a dipeptide Met- Ile can have the following nucleotide sequences.

AUG-AUU
AUG-AUC
AUG-AUA

And if, we deduce amino sequence from the above nucleotide sequences then all the three sequences will code for Methionine and Isoleucine.
