Today's Daily Brain Teaser (Nov 04, 2014)

The Ladder



I'm called by three letters

Though I have a long name.

I'm in all of you,

But I'm never the same.



I'm all coiled up

So that I am quite small,

But if you stretch me out

I'll be really tall.



I could be the root

Of certain disease;

If man can unlock me

He'll solve many mysteries.
