The nucleus controls all functions of the cell. Encoded on the DNA are the "instructions" that the cell needs to create all its proteins (enzymes), hormones and others) and to direct the cells functions. This "genetic" information must be copied and passed on to the next generation of cells. The nucleus also functions to ensure that this copying is carried out correctly.
The nucleus is the "brain of the cell". It is the control center. It contains all information, controls the processes of the cell. It also contains DNA (Deoxyribonucleic acid) which is the blueprint of the cell.

2 major functions:
1. Stores the hereditary material, i.e. DNA
2. Directs cell activity
In a nutshell, it controls all the activities of the cell, and also enables it to divide, make specific substances, etc.....
