Question

What is the application of Somatic Cell Nuclear Transfer Technology?

Options

a

Production of biolarvicides

b

Manufacture of biodegradable plastics

c

Reproductive cloning of animals

Answer
d

Production of organisms free of diseases

Explanation

Somatic Cell Nuclear Transfer (SCNT) is the technology used in reproductive cloning, where the nucleus of a somatic cell is transferred into an enucleated egg cell. This technique was used to produce Dolly the sheep, the first cloned mammal. Option (a) is incorrect—biolarvicides use specific microorganisms, not SCNT. Option (b) is incorrect—biodegradable plastics are produced through genetic engineering or chemical synthesis, not SCNT. Option (d) is incorrect—while SCNT could theoretically be used in therapeutic applications, it is primarily known for reproductive cloning. SCNT is fundamentally a cloning technology. > SCNT = Somatic Cell → Nuclear Transfer = Reproductive Cloning. Answer: c.
