Show answer and explanation
Correct answer: (a) Nucleus of a cell does not play a role in cellular reproduction.
Explanation
The nucleus is the control centre that directs cell division, regulating DNA replication and distribution – so claiming it plays no role is false.
True facts: chromosomes carry hereditary information and are made of DNA and protein (histones).
A gene is the functional segment of DNA that codes for a protein.
