This mitochondrial DNA is -in- the mitochondria, we have two sets of DNA. That DNA is being copied (moved?) to the nucleus for some reason.

I am also not a scientist, but my understanding of the read was that mtDNA is being inserted to repair DNA. I don’t understand all the jargon and processes, though, and this week I don’t have the time to deep dive into it as I would like to.

The nucleus is a safer place for DNA, protected and with more advanced repair mechanisms, so its advantageous to have the genes drift over. The original pre-mitochondrial microbe didn't have a nucleus, and it doesn't matter so much with single celled organisms.
