- For learning about its structure, a nucleus diagram is quite helpful. Important components of its structure include.
- One feature of the nucleus that distinguishes eukaryotic cells from prokaryotic ones is the nuclear membrane.
- Additionally, it has a double-layer structure. It also has phospholipids in it.
- The nuclear envelope, nucleoplasm, or nucleus sap, nuclear matrix, chromatin, and nucleolus are some of the several structures that make up the nucleus.
