Not to detract from the main discussion, but I wouldn't say 'nothing'. Mitochondria have their own DNA, independent of the DNA in the cell's nucleus. Since sperm cell mitochondria do not contribute to the zygote's mitochondria population (they are destroyed), and egg cell mitochondria do, mitochondrial DNA is inherited via the maternal line only. This fact can be used in genetics in various ways.

Did you know that most of the time your computer is doing nothing? What if you could make it do something really useful? Like helping scientists understand diseases? Your computer could even be instrumental in finding a cure for HIV/AIDS. Wouldn't that be something? If you agree, then join World Community Grid now and download a simple, free tool that lets you and your computer do your share in helping humanity. After all, you are part of it, so why not take part in it?
