Question

Animal cloning is commonly achieved by

• A. Embryo splitting
• B. Somatic Cell Nuclear Transfer
• C. Parthenogenesis
• D. In vitro fertilization

Hint:

Example: \[ \boxed{\text{Dolly the sheep}} \] was the first mammal cloned using \[ \boxed{\text{Somatic Cell Nuclear Transfer (SCNT).}} \]

Answer 1

The Correct Option is B

Step 1: Recall the method used in animal cloning. The most common technique for cloning animals is Somatic Cell Nuclear Transfer (SCNT). In this method, the nucleus of a somatic cell is transferred into an enucleated egg cell.

Step 2: Identify the correct option. The reconstructed egg develops into an embryo genetically identical to the nucleus donor. Therefore, \[ \boxed{\text{Somatic Cell Nuclear Transfer}} \] is the correct answer. Hence, \[ \boxed{(B)} \] is the correct answer.
