Question

what is the role of the nucleolus within the nucleus?
a.) to transport proteins
b.) to store dna
c.) to regulate cell division
d.) to construct ribosome subunits

Explanation:

The nucleolus is a structure within the nucleus. Its main function is to construct ribosome subunits. Transporting proteins is more related to structures like the endoplasmic reticulum and Golgi apparatus. Storing DNA is the role of the nucleus as a whole (the nucleolus is part of the nucleus, but DNA storage is a general nuclear function, not specifically of the nucleolus). Regulating cell division is a function that involves multiple cell components like cyclins and CDKs, not the nucleolus.

Answer:

d. To construct ribosome subunits
