1. Nuclear envelope: double membrane surrounding nucleus
2. Nuclear pores: allow the passage of larger molecules (e.g. mRNA), out of the nucleus.
3. Nucleoplasm: granular, jelly-like material making up the bulk of the nucleus.
4. Chromosomes: protein-bound, linear DNA.
5. Nucleolus: small spherical region(s) in nucleoplasm. Manufactures ribosomal RNA and assembles ribosomes.
