Question

Constitutive heterochromatin is

• A. Condensed chromatin
• B. Present in all cells
• C. Made of repetitive bases
• D. All of the above

Answer 1

The correct option is D All of the above

• Constitutive heterochromatin is a certain region of DNA found on the chromosomes of a eukaryotic cell.
  
• The constitutive heterochromatin gets darkly stained due to the highly condensed nature of the DNA in these regions.
  
• This heterochromatin is made up of high copy number tandem repeats (repetitive nucleotides).
  
• So, the correct answer is 'All of the above'.
