usually this is the measuring device of amount of rain fall.

The answer is (A) Mitochondria have their own DNA molecules, separate from the rest of the cell's DNA.
The endosymbiotic hypothesis concerns with the presence of two special organelles, mitochondria and chloroplast within the eukaryotic cell. These two organelles have their own set of DNA that is different from the nuclear DNA of the eukaryotic cell. It is believed that a primordial eukaryotic cell was in a symbiotic relationship with mitochondria-like bacterium. The primordial cell eventually engulfed the mitochondria-like bacterium for ATP production to power itself.
Genetically engineered seed, or GMO, are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.
