It is a double membrane-bound organelle that contains an organism's genetic material.
It is present only in eukaryotic organisms.
It regulates cell functions such as protein synthesis and cell division.
Parts of the nucleus:
The nucleus is made up of various components:
Nuclear envelope: It is made up of 2 lipid layers and has pores in between.
Nuclear lamina: It lies between the inner nuclear membrane and the chromatin's periphery and is made up of lamins and lamin-associated proteins
Nucleolus: The nucleolus is a spherical structure in the nucleus of a cell that is responsible for producing and assembling the cell's ribosomes. Ribosomal RNA genes are also transcribed in the nucleolus.
Nucleoplasm: It is the matrix of the nucleus in which the materials are suspended and is bounded by nuclear membrane.
