Q. Consider the following statements about animal cloning:
1.The new organism produced through animal cloning is genetically identical to original organism.
2.The cloned animal is identical to the donor of the original nucleus in reproductive cloning.
3.It is helpful in conservation of endangered species.
Which of the statements given above are correct?
Answer: D
Notes:
Explanation: All Statements are correct
Statement 1 is correct: Animal cloning is the procedure of creating a whole new multi-cellular organism which is genetically identical to original organism.
Statement 2 is correct: Reproductive cloning involves the implantation of a cloned embryo into a real or an artificial uterus. The embryo develops into a fetus that is genetically identical to the donor of the original nucleus.
Statement 3 is correct: Applications of cloning-
- Biomedical: disease models, bioreactors.
- Agricultural:
- can be used to create copies of animals with highly valued traits, like dairy cow with high milk production
- Livestock improvement
- Genetic improvement
- Conservation of endangered species.
