What exactly is DNA used for? and please also give the website if possible...?

Answer 1

it's the recipe to making ur body! it's basically a chain of codes...after a complex series of events, ur body makes proteins from using this code. the proteins will then be used to create changes in ur body and maintain ur body. (this is a huge generalization, but that is the bottom line.)

here's a website that goes into the history of the discovery of its function.

here's another website...more definition oriented.
