Mitochondria are Flinging Their DNA into Our Brain Cells
Mitochondria are Flinging Their DNA into Our Brain Cells
A new study finds that mitochondria in our brain cells frequently fling their DNA into the cells' nucleus, where the mitochondrial DNA integrates into chromosomes, possibly causing harm.

So my brain is gettin nutted on by my mitochondria?
Kind of, however, a nut contains sperm cells which are gametes. Only reproductive cells are gametes, as they need half the total DNA of all our other cells. This is what allows an eggs and sprem to make a new human. The coolest aspect here is how genetic variation is ensured during this process. But nonetheless, that mitochondrial DNA getting splattered all over your brain is from somatic cells. So it has twice the amount of DNA in it than a nut lol.
