Muscle, nerve, artery and vein
Flay my skin, we are both the same
Beneath a microscope, tell me what you see?
Can those little tissue slices identify me?
Take a drop of blood, test it won’t you please
Certainly my blood separates me from thee
Analyze my chromosomes, test my DNA
Now the differences surely are made plain
Adenine, cytosine, guanine, thymine
Arranged in a double helix, so pristine
It’s just a mix of chemicals, four nucleotides
That makes us different deep inside
