Chromosomes are made of:

  • A RNA mainly, transcribed directly from the nucleolus
  • B Protein mainly, folded into a fibrous keratin-like scaffold
  • C DNA and proteins (mainly histones)
  • D Lipids and DNA bound by a phospholipid bilayer

Correct answer: C. DNA and proteins (mainly histones)

Explanation: Chromosomes are made of DNA tightly wound around histone proteins. This DNA-protein complex is called chromatin.

Concept context
