Chromosomes are made of what?
Answer and explanation
Correct answer: Nucleic acid and proteins
Chromosomes are thread-like structures in the nucleus made primarily of DNA, a nucleic acid, associated with specialised proteins called histones. DNA stores hereditary information, while the proteins help package and organise the long DNA molecule. Therefore the scientifically correct form of option A is nucleic acid and proteins. Water, fats, and starch may occur in cells for other purposes, but none of them alone forms chromosomes or carries their complete hereditary organisation.
