Main Difference: The main difference between nuclear DNA and mitochondrial DNA is, nuclear DNA is the standard 46 chromosome containing DNA in which you inherit 23 chromosome from one parent and the rest 23 from another one.On the other hand, mitochondrial DNA contains just one chromosome, like a circular genome.his chromosome is much shorter and codes for proteins that are used in metabolic purposes. Another main difference is that mitochondrial DNA is only transmitted from mother and never from the father while nuclear DNA is inherited from both, mother and father.
Mitochondrial is DNA passed on to the child by Mom. A fertilized egg will have Mom's mitochondrial DNA, half of Mom's nuclear DNA, and half of Dad's nuclear DNA. When the fertilized egg splits into two, the twins will each have identical nuclear DNA, but not EXACTLY identical mitochondrial DNA. Physical differences in identical twins are contributed, in part, to how much and how similar the mitochondrial DNA each twin inherited from Mom expresses itself.
