medium
Production of human protein in bacteria by genetic engineering is possible because
A
The human chromosome can replicate in the bacterial cell
B
The mechanism of gene regulation is identical in humans and bacteria
C
Bacterial cells can carry out RNA splicing reactions
D
The genetic code is universal
(AIIMS-2018)
Solution
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, genetic code is universal. There is no ambiguity regarding genetic code. It means that each codon codes for the same amino acid in all organisms including bacteria, plants and animals.
