Which organelle in the cell, other than nucleus, contains DNA?

1. DNA (Deoxyribonucleic acid) contains the genetic instructions for the development, functioning, growth and reproduction of all known organisms. 2. In eukaryotic cells, the vast majority of DNA is located within the nucleus. 3. However, some DNA is also found in other organelles. 4. The Mitochondrion (plural: mitochondria), often called the 'powerhouse of the cell', contains its own circular DNA (mtDNA), which encodes some mitochondrial proteins and RNAs. 5. In plant cells, chloroplasts also contain their own DNA. 6. Centrioles are involved in cell division, Golgi apparatus in protein modification and transport, and Lysosomes in cellular digestion; these organelles do not contain their own DNA. 7. Therefore, the Mitochondrion is the organelle, other than the nucleus, that contains DNA.
