Full Answer

The nucleus of a cell contains most of that cell's genetic material. Its job is to maintain the integrity of the cell while controlling its activities. The nucleus is separated from the cytoplasm by a membrane called a nuclear envelope.This helps to protect the cell's chromosomes which is where the DNA is located.
