DNA replication and all that jazz

Submitted by kgould on Sat, 11/03/2007 - 6:20pm.

I took AP Biology in high school last year and we went into this topic, that of DNA, deeply. Or, at least, we tried to. I'm not sure how much of it I actually absorbed. (We were forced to memorize all of the proteins, ick).

In any case, this time around, once again, the subject seems much more approachable. The fact that we didn't go down into the tiniest details about DNA (DNA polymerase, ligase, blah blah blah) makes it much easier to understand. 

Just one question: is the chance of mutation affected by external sources? (Smoking, drinking, pollution, disease...?) Can something that you put in your body (or are exposed to) affect how your DNA is replicated?
