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
