Even if there's a "good reason" that life forms in a specific way (e.g. water + carbon based, RNA & DNA encoding information, etc.) there's very little reason that DNA should encode proteins in exactly the way ours does (on Earth-based life, AFAIK the code is nearly universal, indicating common origin).
