Which of the following features of genetic code does allow bacteria to produce human insulin by recombinant DNA technology?
Genetic code is nearly universal
The correct option is D.
Explanation of correct option:
Explanation of incorrect options:
Option A:
Genetic code is specific means one codon codes for only one amino acid.
Option B:
Genetic code is unambiguous and specific because one codon codes for only one amino acid.
Option C:
The genetic code is considered to be redundant because many codons can encode the same amino acid residue.
Final answer: "Genetic code is nearly universal" is the features of genetic code that allows bacteria to produce human insulin by recombinant DNA technology.
