Ans. A.
In mammalian cells, only about 1% of the total cellular DNA is composed of mitochondrial DNA whereas in other organisms (for example in the egg cells of amphibians) there is a much higher percentage of mitochondrial DNA.
DNA is located in nucleus. DNA is also present in mitochondria (butless than 0.1% of the total DNA).
