Question

E.coli is used in the production of

• A. Rifampicin
• B. LH
• C. Interferon
• D. Ecdysone

Answer 1

The correct option is C

Interferon

The correct option is : C.

The explanation for the correct option:

1. E. coli is a rod-shaped Gram-Negative, facultative, anaerobic bacteria.
2. Because of the remarkable efficiency with which DNA molecules are introduced into cells, it is a favoured host for gene cloning.
3. Because of its rapid growth and capacity to express proteins at very high levels, E. coli is a desirable host for protein synthesis.
4. In reaction to the presence of infections, host cells create and release interferons.
5. These are signalling proteins.
6. In response to dsRNA, host cells produce interferon proteins encoded by host genes.
7. E. coli produce interferons using recombinant DNA technology.

The explanation for the incorrect options:

Option A

1. It's an antibiotic that's used to treat a wide range of infections.
2. Bacterium Amycolatopsis rifamycin produces this naturally.
3. Tuberculosis is treated or prevented using this drug.

Option B

1. The anterior pituitary gland secretes luteinizing hormone.
2. It influences sexual development in person.

Option D

1. In insects, it is a steroidal hormone released by the prothoracic gland.
2. It is involved in the stimulation of metamorphosis.
3. It helps in the regulation of moulting in insects.

Final answer: E.coli is used in the production of Interferon.
