Q. Production of a human protein in bacteria by genetic engineering is possible because :
A) bacterial cell can carry out the RNA splicing reactions
B) the human chromosome can replicate in bacterial cell
C) the mechanism of gene regulation is identical in humans and bacteria
D) the genetic code is universal
Explanation
[Solution from source] Because the genetic code is universal, bacterial ribosomes read a human gene's codons as the same amino acids and so make the human protein. Bacteria cannot splice introns (cDNA is used for that reason), and gene regulation differs between bacteria and humans. Answer (4).
