As I mentioned some sequences kill the animal. But within large limits each
protein (and thus the DNA behind it) are free to wander through a large
number of viable possibilities. There are something like 10^94 different
permutations of the cytochrome c molecule that will function just fine and
dandy in your body. (see Hubert Yockey, Information Theory and Molecular
Biology, p. 59). There are a total of 10^137 possible permutations of a
sequence that long. So, yes there are limits, but they aren't very limiting.
