Here is a new one.

DNA (to the tune of TNT by ACDC)

Oi! Oi! Oi! Oi! Oi! Oi! Oi! Oi!

See me divide up in your nucleus on your micro-screen
I'm all of you that you can get
If you know what I mean
Proteins to the left of me, lipids to the right
Aint got no oxy, but I got moxy
Don't you start a fight

"Cus I'm DNA
I'm Dynamite
(DNA) I'm wound up tight
(DNA) I have secrets to tell
(DNA) I'm in your cells!!!!

I'm Adenine! Guanine! Cytosine!
And Thymine man!
Nitrogen bases, a phosphate group
Understand?
G binds to C
A binds to T
A double helix plan
I run your life!
I control your cells!
So don't you mess me around!

Cus I'm DNA!
I'm dynamite
(DNA) And I'm wound up tight!
(DNA) I have secrets to tell
(DNA)I'm in your cells!
