We start the story when Mom met Dad And they danced all night and he took her home It might have been all the wine they had But they rolled the dice and won your genome Then you grew and you grew and one day you were you And you looked like your father and mother If you're looking for someone convenient to blame You can take your pick it's one or the other DNA, you're in my heart DNA, in fact you're in every part of my body Each cell has a nucleus, each nucleus has chromosomes And DNA, baby, that spells DNA Guanine met Cytosine, fell in love And then Thymine got busy with Adenine They sent the messenger-RNA To the ribosome to make more protein And while it's killing you dead it will mess with your head And it's the light in the dark that will guide you It's the pages and pages of what you are like In the giant book that's hidden inside you DNA, you're in my heart DNA, in fact you're in every part of my body Each cell has a nucleus, each nucleus has chromosomes And DNA, baby, that spells DNA If it says TGGTCGAAC Then you might get the cancer If it says GTCACGACAGG Then you shouldn't eat shrimp or nuts If it says TATACACATATCCTCGT Then you'll probably wish that you didn't know The time will come when you're almost gone And you try to guess but you'll never know You do your best and you soldier on Every day you're here till it's time to go All the good things and bad that you do or don't have You can find out for sure if you got ‘em But there's a spiraling staircase that you're falling down And you're nothing but dead at the bottom DNA, you're in my heart DNA, in fact you're in every part of my body Each cell has a nucleus, each nucleus has chromosomes And DNA, baby, that spells DNA
