It makes nucleoli during interphase:
Correct answer: B. Secondary constriction
- A. Primary constriction
- B. Secondary constriction
- C. Centromere
- D. Telomere
Explanation
Some chromosomes may have a point of union, other than primary constriction, along the length of chromatids. This is called secondary constriction, also known as nucleolar organizer. It gives rise to nucleoli during interphase.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
