Nucleus

The nucleus is the center of a cell, which controls all cell activities and also contains DNA. 
Nucleus contains all genetic material of the cell, and Its like the brain of the cell. The genetic material inside the cell is called a genome of the cell. Within the nucleus DNA in the chromosomes are duplicated before cell division and RNA is synthesized. It usually takes up about 10 percent of the cell's volume, and consists of the following main parts: Nucleolemma or nuclear membrane, Nuclear sap or karyolymph or nucleoplasm, Chromatin network or fibres, Nucleolus, and Endosomes. The nucleus is kinda like your mini brain, it controls all the little things that make up who you are. The nucleus was the first of the cell organelles to be discovered by scientists. Each human cell contains around 6 feet of DNA which is very packed and organized with proteins.

• The nucleus has a double membrane (the nuclear envelope) around it.
• The nuclear membrane has pores allowing the movement of substances through it.
• The nuclear membrane joins up with the endoplasmic reticulum.
• The nucleus contains chromosomes which are made of DNA and associated proteins called histones.
• There may be at least one dark stained body called a nucleolus.
• The nucleus contains genes that hold the information needed to make proteins.
