Q. Consider the following statements regarding the applications of Somatic Cell Nuclear Transfer (SCNT):
1.SCNT can be used for reproductive cloning, a process famously demonstrated by the creation of Dolly the sheep.
2.Therapeutic cloning uses SCNT to produce stem cells that are genetically identical to the donor, reducing the risk of immune rejection in regenerative medicine.
3.SCNT is currently the primary and most cost-effective method used for the commercial mass production of food crops.
Which of the statements given above are correct?
Answer: A
Notes:
Explanation:
- Statements 1 and 2 are correct: Somatic Cell Nuclear Transfer (SCNT) is used for both cloning whole organisms and creating patient-specific stem cells.
- Statement 3 is incorrect: Somatic Cell Nuclear Transfer (SCNT) is an animal biotechnology tool. Mass production of food crops relies on seed technology, tissue culture, or other genetic modifications, not nuclear transfer into egg cells.
