my biochem prof taught us a great song to help us study...heheh.. (sing to the tune of "The Flintstones")...thought I'd share it with you all. Histones btw is a crazy protein that binds our crazy long DNA together, in those nice lil' crazy chromosome packages. CRAZY! lol...I've seriously gone...Yaba-daba-doo!

Histones! Meet the histones!
They're a basic protein family
There are just 4 subtypes
They're conserved evoluntionarilyyy...

Two each of each histone do their thing.
Forming just like beads upon a string.
H1 binds the complex
And it inhibits new transcription
And the creation...of new mRNA!
