Somatic Cell Nuclear Transfer (SCNT) technology is primarily applied for which one of the following purposes?

Question

Accepted Answer

B. Reproductive cloning of animals, the technique used to clone Dolly the sheep. Somatic Cell Nuclear Transfer involves removing the nucleus from a body cell and inserting it into an egg cell whose own nucleus has been removed, and this is precisely the technique that produced Dolly the sheep, making it the foundational method behind reproductive cloning of animals. It is not a genetic modification technique for crops, a genome sequencing method, or a pre-implantation diagnostic tool, each of which uses entirely different underlying processes. Hence option B correctly identifies its real application.

Answer

A. Producing genetically modified crop varieties resistant to pests

Answer

B. Reproductive cloning of animals, the technique used to clone Dolly the sheep

Answer

C. Sequencing the complete genome of a newly discovered species

Answer

D. Diagnosing genetic disorders in a human embryo before implantation
