mutation of e.coli

[xander4427 at my-deja.com]

Hi, I'm in college and we are doing an experiment
with e.coli. We will expose the e.coli to
some chemical products and then we will check its
dna (genetic code) if there are any changes. If
someone knows the kind of chemicals products we
should use, tell us, your help will be gladly
accepted. If you have any other information that
might help us, write us back

                  thank you
                              Alex
