What are Mitochondrial nuclear organelle?

Quoted---- Mitochondrial DNA (mtDNA) is the DNA located in organelles called mitochondria, structures within cells that convert the energy from food into a form that cells can use. Most other DNA present in eukaryotic organisms is found in the cell nucleus. Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived from the circular genomes of the bacteria that were engulfed by the early ancestors of today's eukaryotic cells.

Each mitochondrion is estimated to contain 2-10 mtDNA copies ----quoted---- information quoted from http://en.wikipedia.org/wiki/Mitochondrial_DNA the link mentioned above will explain it for you. Please note some of the question you asked involves detailed explanation directly from the source material and this will border on plagiarism and copy right infringement.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
