Why are fewer polypeptide sequences encountered biologically than are theoretically possible?
A) There is no way to make all the theoretical possibilities.
B) The phosphodiester linkages don't allow for all the possibilities.
C) Not all have useful structural and functional properties.
D) Not all of the possibilities can be broken down.
