Actually, you're on the right track.

For example, if you look at the triplet codons which code for amino acids, you can see that (in general) the more detrimental a mutation (such as positively charged residue to negatively charged), the more the codon has to be changed.

Check out http://en.wikipedia.org/wiki/Genetic_code

So I guess one can say that there is a mechanism in place to minimize the negative effects of random mutation. The mutations themselves are still random, however.

Obviously a great deal of nuance was left out of this and my previous comment. Genetics is big, and really can't be done justice in a /. thread.

Epigenetics, in my mind, is something different. To quote from your link:
"However, there is no change in the underlying DNA sequence of the organism"

It is simply control of which genes are expressed, not control of which genes are present in the genetic code.

Though, my definition of mutation could be completely off? Please correct me if so.

You're definitely on their list. The question to ask next is what list it is.

Working...
