Production of a human protein in bacteria by genetic engineering is possible because:
Correct answer: D. The genetic code is universal.
- A. The human chromosome can replicate in bacterial cell
- B. The mechanism of gene regulation is identical in humans and bacteria
- C. Bacterial cell can carry out the RNA splicing reactions
- D. The genetic code is universal.
Explanation
Genetic code may be defined as the sequence of nucleotides in polynucleotide chain which determines the sequence of amino acids in a polypeptide chain. Thus the genetic code is universal. There is no ambiguity regarding the genetic code. It means that each codon codes for the same amino acid in all organisms including bacteria, plants and animals.
