Question

Human insulin can be mass-produced using genetically modified bacteria. The human insulin gene is added to a bacterial strain, and the bacteria will produce the human protein. This process demonstrates that

• A. Bacteria have mechanisms for identifying and translating foreign DNA.
• B. DNA is functionally identical in all organisms.
• C. Humans and bacteria are closely related.
• D. Humans are prokaryotic.

Answer 1

The correct option is A Bacteria have mechanisms for identifying and translating foreign DNA.

Human insulin can be mass produced using genetically modified bacteria, human insulin gene is added to the bacterial plasmid, which replicates and produces the protein. DNA in all organisms is chemically same but functionally different.

So, the correct answer is 'Bacteria have mechanisms for identifying and translating foreign DNA'
