Which of the following is true for nucleolus?

AIt takes part in spindle formation.
BLarger nucleoli are present in dividing cells.
CIt is a site for active ribosomal RNA synthesis.
Correct Answer
DIt is a membrane-bound structure.

Solution

Nucleolus is the spherical structure present in the nucleoplasm.

It is not membrane-bounded and thus its content is continuous with nucleoplasm. It gets disappear during cell division.

But it provides the site for ribosomal RNA synthesis and also takes part in protein synthesis.

Hence, option C is correct.
