Below is the first page of a real DNA sequence that was collected by scientist

at Argonne National Laboratory.

Here's the color coding.  If you can't read the letters, check the peaks on the graph.

A...adenine is green

T...thymine is red

C...cytosine is blue

G...guanine is black

If you do all of the pages you end up with a sequence of 800 base pairs that looks like this:

Obviously, doing this by hand would take a long time.  Luckily, a computer

can do this for you.

But once you have the sequence what can you really do with it?
