-It is a double membrane-bound organelle mainly found in eukaryotic cells.
-It contains the cell’s hereditary information and controls the cell’s growth and reproduction.
-It is the command center of a eukaryotic cell and is commonly the most prominent organelle in a cell accounting for about 10 percent of the cell’s volume.
-The nucleus is separated from the rest of the cell or the cytoplasm, by a nuclear membrane.
-As the nucleus regulates the integrity of genes and gene expression, it is also referred to as the control center of a cell.
-The structure of a nucleus encompasses the nuclear membrane, nucleoplasm, chromosomes, and nucleolus.
-The nuclear membrane is a double-layered structure that encloses the contents of the nucleus. The outer layer of the membrane is connected to the endoplasmic reticulum.
-Nucleoplasm is the gelatinous substance within the nuclear envelope. It supports the nucleus by helping to maintain its shape.
-Contained within the nucleus is a dense, membrane-less structure composed of RNA and proteins called the nucleolus.
-The nucleus is the organelle that houses chromosomes.

Note: The chromatin is further classified into heterochromatin and euchromatin based on the functions. The former type is a highly condensed, transcriptionally inactive form, mostly present adjacent to the nuclear membrane. On the other hand, euchromatin is a delicate, less condensed organization of chromatin, which is found abundantly in a transcribing cell.
