Question

Common bacteria used in genetic engineering is:

• A. E. coli
• B. Diplococcus
• C. Rhizobium
• D. Spirillum

Answer 1

Answer: (A)

E. coli

Answer 2

Artificial gene manipulation is known as genetic engineering. The bacterium Escherichia coli is widely used in genetic engineering experiments as: (i) Human insulin chains ( $\alpha$ and $\beta$ chains) are synthesized within the E. coli. (ii) Hormone somatostatin is also produced within the bacterium E. coli.
