Show Answer
Answer : c
Hints & Solution
(c) Genetic code is the relationship of amino acid sequence in a polypeptide and nucleotide/ base sequence in $mRNA /$ antisense strand of DNA. It is universal, i.e., a codon specifies the same amino acid in all organisms, non-overlapping, i.e., adjacent codons are independent with no base being member of two codons, degeneracy, i.e., some amino acids are coded by more than one codon, hence the code is degenerate, unambiguous, i.e., one codon codes for only one amino acid.
