Ok. Many biology books, including those used for "biol 1" deal with
this at some level.

A book I might suggest...

D P Clark & L D Russell, Molecular Biology made simple and fun, 2/e.
Cache River Press, 2000. ISBN
1889899046. This book is intended for both a general audience and a
wide range of science students. It presents the basics
of molecular biology in a way that is readable and fun, yet
scientifically quite sound. It may be helpful as an introduction for
some students. Others will just find it fun. 

     For a brief preview of the book, check their web site:
http://www.cacheriverpress.com/ 


It is an inexpensive paperback (about $35 I think), available mainly
thru them directly. It is readable by high school kids or your mother.
So it would not be a big investment to get it, and you could easily
find a good home for it when/if done. Could be a good place to start,
if you would like to do some reading on your own.


And by the way, there is much need for people who combine business and
biology. The biotech industry has been one of the great booms of the
last couple of decades, with -- presumbaly -- much more to come.
