Question

Chromatin material which remains condensed during interphase is called

• A. Heterochromatin
• B. Euchromatin
• C. Chromonemata
• D. Megachromatin

Answer 1

The correct option is A Heterochromatin

• Chromatin material which remains condensed during interphase is called heterochromatin.
  
• Heterochromatin refers to the certain regions of DNA found on the chromosomes of a eukaryotic cell.
  
• The heterochromatin gets darkly stained due to the highly condensed nature of the DNA in these regions and has higher ribonucleic acid content.
• This heterochromatin is made up of high copy number tandem repeats (repetitive nucleotides).
• So, the correct answer is 'Heterochromatin'.
