Ribosomes are assembled in the cytoplasm, not the nucleolus. The nucleolus produces ribosomal subunits, but these must be exported into the cytoplasm through nuclear pores in order to be assembled in the cytoplasm into fully functioning ribosomes.

sweet, simple and effective explanation. Great! Thanks for helping me in my class presentation, my topic was nucleus and its functions. :)

Very well explained, it would have been good though if you had explained what are the substances and molecules that interact with the nucleus such as CO2, Oxygen among other bunch of stuff that i'm actually looking for.

" The nucleus is surrounded by a system of two concentric membranes, called the inner and outer nuclear membranes. The outer nuclear membrane is continuous with the endoplasmic reticulum, so the space between the inner and outer nuclear membranes is directly connected with the lumen of the endoplasmic reticulum."
