Web29 mei 2024 · DNA (deoxyribonucleic acid) is the cell’s genetic material, contained in chromosomes within the cell nucleusand mitochondria. Except for certain cells (for example, sperm and egg cells and red blood cells), the cell nucleus contains 23 pairs of chromosomes. Do mitochondria have DNA? WebInside the nucleus, DNA is folded up into a complex molecule called chromatin, which is further organised into chromosomes. These chromosomes are stored in the nucleoplasm, which is a matrix similar to the cytoplasm. The nucleus is surrounded by double layered membrane called the nuclear envelope.
