write about nucleus of cell
Answers
Answer:
The cell nucleus contains all of the cell's genome, except for a small fraction of mitochondrial DNA, organized as multiple long linear DNA molecules in a complex with a large variety of proteins, such as histones, to form chromosomes. The genes within these chromosomes are structured in such a way to promote cell function. The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expression—the nucleus is, therefore, the control center of the cell. The main structures making up the nucleus are the nuclear envelope, a double membrane that encloses the entire organelle and isolates its contents from the cellular cytoplasm, and the nuclear matrix (which includes the nuclear lamina), a network within the nucleus that adds mechanical support, much like the cytoskeleton, which supports the cell as a whole.

Nucleus is a somewhat large, spherical body present inside the cytoplasm. It is the most essential component of the cell. If removed, the cell dies. It contains nucleolus, which have centrosome from which a new cell arises. It thus helps in cell division. It also contains DNA and gened which helps in transmission of hereditary characters to offsprings.
