Question

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 mechanism of gene regulation is identical in humans and bacteria.
• C. The human chromosome can replicate in bacterial cell.
• D. The genetic code is universal.

Answer 1

The correct option is D The genetic code is universal.

Production of a human protein in bacteria by genetic engineering is possible because the genetic code is universal. The genetic code is the set of rules by which information encoded within genetic material that is the DNA or mRNA sequences which are translated into proteins by living cells. The genetic code is highly similar among all organisms and can be expressed in a simple table with 64 entries.
