Auguri mamma – A Biologist’s Mother’s Day Song

A Biologist’s Mother’s Day

To make one me you just add
Half of mom and half of dad
That is what I once believed
But now I know that I was wrong
You gave so much to me mom
Besides one half a set of genes

You gave me nutrients, transcription factors
Nearly everything that matters
Plus my prenatal environment (transplacental inheritance)
mRNA, mitochondria
That back in the day once belonged to ya (they’re cytoplasmic)
I just wanna thank you for supplying them

Just like two strands of DNA are spirally entwined
Your nature and your nurture inspiringly combine
Scientists remind me and I find that it is true
Slightly more than half of everything I am is thanks to you
Slightly more than half of everything I am is thanks to you

Mitochondria power the cell
And they have DNA as well
Transcription factors modulate transcription
Since they’re in the cytoplasm
The egg’s the only one who has ‘em
And sperm I guess they don’t have the ambition

My sex determination gene means that I’m a guy (I’m a guy)
You gave me one X chromosome, dad gave me one Y
X has over a thousand genes, while Y has less than 92
That’s why slightly more than half of everything I am is thanks to you
Slightly more than half of everything I am is thanks to you

I roomed in your womb for nine months and I’ve never paid the rent
Your glucocorticoids have shaped my hypothalmic development
I’ve took your blood and sucked it dry of every nutrient (it’s gross but true)
Sometimes I wonder where the time went (where did it go?)
Sometimes I wonder where it all went

I know I’ll never understand all you have done for me (I’m not that smart)
But since you paid for college I’ll get my B. S. degree (bachelor of science)
And I have learned it’s not BS but absolutely true
Slightly more than half of everything I am is thanks to you
More than half of everything I am is thanks to you

You gave me nutrients, transcription factors
Nearly everything that matters
mRNA, mitochondria
That back in the day once belonged to ya

Nutrients, transcription factors
Everything that really matters
mRNA, mitochondria
That back in the day once belonged to ya

Singing: Nutrients, transcription factors
Nearly everything that matters
mRNA, mitochondria
That back in the day once belonged to ya

(It’s not an even 50/50 split, you get a disproportionate share of your DNA coming from your mom. Really important)

Just like two strands of DNA are spirally entwined (double helix)
Your nature and your nurture inspiringly combine
Scientists remind me and I find that it is true
Slightly more than half of everything I am is thanks to you (it’s science)
Slightly more than half of everything I am is thanks to you
Slightly more than half of me is thanks to you
