Worked practice questions

In reproductive cloning, a new organism is produced by fusing an enucleated ovum with:

Flower-to-flower pollination
Routine yearly vaccination
Cellular waste excretion
The nucleus of a somatic cell

Show answer and solution

Correct answer: D. The nucleus of a somatic cell

1. Reproductive cloning avoids the need for a sperm. 2. It is done by fusing the nucleus of a somatic cell with an enucleated ovum. 3. A sperm is exactly what cloning avoids; red blood cells have no nucleus to donate and pollen grains belong to plant reproduction. 4. The sperm option traps students who assume normal fertilisation is involved. _Source: Balbharati (Maharashtra Board) Class 10 Science & Technology Part 2, Ch 8 "Cell Biology and Biotechnology", p.103_
