The nucleus of an eukaryotic organism is an organelle surrounded by a nuclear envelope, which contains nuclear pores. The pores allow the transportation of material between the nucleus and the cytoplasm through nucleocytoplasmic transport. [1] The nuclear pore is composed of multiple proteins, allowing the entry of small water soluble molecules and proteins of a small molecular weight from the cytoplasm into the nucleus. The nuclear pores further allow instructions from the nucleus to enter the cytoplasm in the form of ribonucleo protein complexes.
