Solution

The correct option is D Genetic code is nearly universal
Genetic code is nearly universal as a particular codon codes for the same amino acid across organisms, with some exceptions in mitochondrial codons and in some protozoans.
Hence, bacteria can have the same codon coding for the same amino acid as that of human beings.
Example: UUU codes for phenylalanine in bacteria and human beings.

Genetic code is degenerate because more than one codon can code for an amino acid.

Genetic code is unambiguous and specific as a particular codon always codes for only one amino acid.
