Mitochondria contain there own DNA.
Similar to choloroplasts: have a double membrane and have evolved from prokaryotic cells that 'invaded' eukaryotic cells in early evolutionary history - around 2 billion years ago.
Made themselves invaluable - providing pathways and enzymes that help the cell to survive.
Get your many mitochondria from a few mitochondria cells that were in mother's egg cells, genes are passed down. When the cell divides, the mitochondria are shared out between the daughter cells.
Human M.chondria contain 37 different genes - not as well protected as ones in nucleus - also prone to mutation - some mutations are harmful - mutant M.chondria genes have been linked to number of diseases.
M.chondria aren't self sufficient in…
