Chemical composition of chromosome:(a)DNA and lipids(b)DNA and carbohydrates(c)Proteins and lipids(d)DNA and proteins

The correct answer is:

(d) DNA and proteins

Chromosomes are complex structures found in the nucleus of cells that contain genetic information. The primary components of chromosomes are DNA (deoxyribonucleic acid) and proteins. DNA carries the genetic instructions necessary for the development, functioning, and reproduction of all living organisms. Proteins play a crucial role in packaging and organizing the DNA, as well as facilitating various cellular processes related to gene expression, replication, and more. While lipids and carbohydrates are important components of cells, they are not the primary constituents of chromosomes.
