What are chromosomes primarily composed of?

Explanation:
Chromosomes are made primarily of DNA. DNA stores the genetic information as sequences of nucleotides that define genes. In cells, DNA is tightly packed with histone proteins to form chromatin, which condenses into chromosomes during cell division. The proteins help package and regulate access to the DNA, but the information that genes convey resides in the DNA sequence, making it the main component. Lipids and carbohydrates do not form the core structure of chromosomes.
