The function of nucleolus is to make:

Explanation

The nucleolus transcribes ribosomal RNA and assembles it with proteins into the ribosomal subunits, which are then exported through the nuclear pores. Cells that make a great deal of protein have correspondingly prominent nucleoli. Lysosomes are budded off by the Golgi apparatus, and rDNA is the template the nucleolus reads rather than something it makes.
