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 obtaine, e.g., lle (Isoleucine) has three codons AUU, AUC, AUA. Hence, a dipeptide Met-lle can have the following nucleotide sequence.
(i) AUG-AUU (ii) AUG-AUC (iii) AUG-AUA
And if, we deduce amino acid sequence from the above nucleotide sequences, all the three will code for Met-lle.
Q. 2. A single base mutation in a gene may not 'always' result in loss or gain of function. Do you think the statement is correct? Defined your answer.
