- Nucleus | Definition, Function, Structure, Facts | Britannica
Nucleus, in biology, a specialized structure occurring in most cells (except bacteria and blue-green algae) and separated from the rest of the cell by a double layer, the nuclear membrane
- Cell nucleus - Wikipedia
The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expression Because the nuclear envelope is impermeable to large molecules, nuclear pores are required to regulate nuclear transport of molecules across the envelope

The nucleus is a defining, membrane-bound compartment found within eukaryotic cells (animals, plants, fungi, and protists) It serves as the cell’s central command center, regulating all cellular activities and holding the master blueprints for the entire organism
- Cell Nucleus - Definition, Structure, Function
The nucleus is a large, membrane-bound organelle in eukaryotic cells that contains the cell’s genetic material in the form of DNA Its primary role is to regulate gene expression, mediate replication, and coordinate cell activities like growth and metabolism
