The cell nucleus contains the majority of the cell's genetic material in the form of multiple linear DNA molecules organized into structures called chromosomes. Each human cell contains roughly two meters of DNA.
A human cell has genetic material contained in the cell nucleus (the nuclear genome) and in the mitochondria (the mitochondrial genome). In humans the nuclear genome is divided into 46 linear DNA molecules called chromosomes, including 22 homologous chromosome pairs and a pair of sex chromosomes. Some eukaryotic cells (plant cells and fungal cells) also have a cell wall. 2  Inside the cell is the cytoplasmic region that contains the genome (DNA), ribosomes and various sorts of inclusions. 3  The genetic material is freely found in the cytoplasm.
