Question

The organelles that contain their own genetic material are 

(a) Mitochondria, Vacuoles 

(b) Plastids, Golgi complex 

(c) Mitochondria, Plastids 

(d) Ribosomes, NucleolusA

Answer 1

(c) Although most of a cell's DNA is contained in the cell nucleus, mitochondria have their own independent genomes. As mitochondria contain ribosomes and DNA, and are only formed by the division of other mitochondria, it is generally accepted that they were originally derived from endosymbiotic prokaryotes. Plastid DNA exists as large protein-DNA complexes associated with the inner envelope membrane and called 'plastid nucleoids'. Each nucleoid particle may contain more than 10 copies of the plastid DNA.
