6 0

Answer:

<em>The correct option is C) Mitochondrial DNA can be traced for generations.</em>

Explanation:

The mitochondria are the organelles of the animal cell which contain their own genome. This genome also has the ability to produce proteins. The mitochondrial DNA passes from the mother to the children and remains identical. We can say that the mother and the children will possess the same mitochondrial DNA. In this manner, the mitochondrial DNA can be traced for generations as it remains the same for generations.
