The nucleus is able to control and regulate the rest of the cell(it basically tells it what to do). The DNA is made up of chromosomes,the DNAs shape is a double helix and is tightly packed inside of the nucleus. The job of the DNA is to regulate the rest of the cell and tell the cell what kind of cell it is and what job it needs to do(ex all cells are different so the dna determines the type of cell like a bone cell or blood cell) this ties in with genetic because your dna makes up your cells and your cells make up who you are.
