The nucleus is a structure found in cells that is separated from the rest of the cell by a double membrane called the nuclear membrane. 

The main function of the nucleus is to store genetic information. 

The nucleus houses DNA and RNA in structures called Chromosomes or Chromatin.   

Genetic information in the nucleus tells the cell what proteins need to be produced.
