A Conversation for Mitochondria - Power Plants of the Cell

Just wanted to say thanks for a very illuminating entry. I didn't know about the mitochondrial DNA being maternally-inherited. How interesting!

I heard a chap on Radio Scotland today saying that he analyses mitochondrial DNA (which is maternally inherited). From what he has seen, he reckons that 95% of Europeans are descended from just seven (7) women who lived between 10 000 and 45 000 years ago! I thought that was quite amazing.

You should have watched Horizon a few weeks ago (assuming you are British .
It was about supervolcanoes (hundreds of times more powerful than Krakatoa) and apparently a supervolcano erupted around then and they think that is what might have caused this.
Its a contoversial topic mind as not all scientists agree that mitchondrial DNA mutates regularly like a clock which is what they use to estimate this timescale.

That is why a recent child was deemed genetically modified. It was created from a donor egg and a fertilised nucleus. The nucleus contained DNA from a mother and father and the egg had DNA from the donor inside the mitachondria. In effect the child had 3 genetic parents.
