Cells - Components of the Nucleus

The video tutorial explains the nucleus as the largest structure in eukaryotic cells, acting as the control center where genetic instructions are stored. It describes chromatin, which condenses into chromosomes during mitosis, and the nuclear membrane, which separates the nucleus from the cytoplasm. The nuclear membrane is dotted with ribosomes and is continuous with the endoplasmic reticulum. Nuclear pores allow molecule transport, including mRNA. The nucleolus, located in the nucleus, produces ribosome material and regulates cell division.

How does the nuclear membrane facilitate the transport of molecules?

What role does the nucleolus play within the nucleus?
