Chromosomes are Made up of

Q. Chromosomes are made up of 

(1) DNA only 

(2) protein only 

(3) DNA and protein 

(4) RNA only

The correct answer for this question is option 3 i.e. DNA and protein.

• Chromosomes are a thread-like structure and each chromosome is composed of proteins and a single molecule of DNA (deoxyribonucleic acid)
• Chromosomes are referred to as bundles of tightly coiled DNA that are located within the nucleus of the cells in the body of a human being
• It is the unique structure of chromosomes that keeps DNA tightly wrapped around histones, spool-like proteins
• The DNA is protected from getting tangled and damaged by chromosomes
• Each chromosome consists of thousands of genes that code for multiple proteins in the body of the human being
• The main function of the chromosomes, made up of proteins and DNA, is to carry the genetic material from one generation to the other
