Question

Which of the following technique is commonly used in animal cloning?

• A. Polymerase Chain Reaction (PCR)
• B. CRISPR-Cas9
• C. Somatic Cell Nuclear Transfer (SCNT)
• D. Gel Electrophoresis

Hint:

Somatic Cell Nuclear Transfer (SCNT) is a technique used to create genetically identical organisms by transferring the nucleus of a somatic cell into an enucleated egg cell.

Answer 1

The Correct Option is C

Animal cloning involves creating an organism that is genetically identical to another. The most commonly used technique for animal cloning is Somatic Cell Nuclear Transfer (SCNT).
(1) Polymerase Chain Reaction (PCR): PCR is used to amplify DNA, but it is not directly related to animal cloning. Hence, this is not the correct answer.
(2) CRISPR-Cas9: CRISPR-Cas9 is a gene-editing tool, but it is not used for animal cloning. It is used for modifying specific genes, not for creating clones. Hence, this is not the correct answer.
(3) Somatic Cell Nuclear Transfer (SCNT): This is the correct answer. SCNT is the primary technique used in animal cloning. It involves transferring the nucleus of a somatic cell into an egg cell that has had its nucleus removed, creating a genetically identical organism.
(4) Gel Electrophoresis: Gel electrophoresis is used for separating and analyzing DNA, RNA, or proteins, but it is not used for animal cloning. Hence, this is not the correct answer.
Conclusion: The correct answer is Option 3: Somatic Cell Nuclear Transfer (SCNT) as it is the technique most commonly used in animal cloning.
