Happy Mother’s Day Mom! Thanks for giving me your nose!
Mitochondrial DNA (or mtDNA) is the DNA that we inherit from our mother.
The DNA we inherit from Pops gets recombined, rearranged, and at least some of it even destroyed in the process of building our body.
But not the Mitochondrial DNA.
Within each and every one of our cells, Mitochondrial DNA sits there, fully intact. Perfect. Unmolested. Pristine.
This is how scientists are able to trace the maternal linage of human beings all the way back to a single woman who lived roughly 200,000 years ago, the earliest common ancestor to all living human beings.
So on this day, Mother’s day, the day we tag to honor our mothers (with a grilled wing dinner, grilled chicken salad, hot buttered corn on the cob, a glass of wine and some sort of dessert to be named later) remember that even if your mother isn’t physically with you anymore, there is a part of her, perfectly intact, not only in your heart, and in your soul, but literally in every single cell in your body.
