What are the functions of various parts of nucleus of a cell??

Dear student,

Nucleus   is the largest organelle present in the eukaryotic cells. In mammalian cells, the size of the nucleus typically varies from 11 to 22 µm in diameter. It is spherical in shape.

 

 

Structural component	Feature
Nuclear envelope	The nucleus is enclosed by a double layered cellular membrane called the nuclear envelope.
Nucleoplasm	The nucleus contains a nuclear sap, enclosed by the nuclear envelope, which is known as the nucleoplasm. This holds the nucleoli and suspends the chromatins.
Nucleolus	The nucleolus is a sub-organelle present inside the nucleus. It can be observed as a dark spot under the microscope. Nucleoli are made up of proteins, ribosomal RNA (rRNA), and ribosomal DNA (rDNA).
Chromatin network	DNA gets associated with protein molecules to form chromatins. Chromatins are present in the nucleoplasm.
