Body Symmetry of Phylum Chordata Although chordates come in many shapes and sizes, they share the four characteristics listed above and they also all have bilateral symmetry. If you divide a chordate in half, you will get two equal pieces that are mirror images of each other.
The Cyclic Groups have one rotational axis of symmetry, for example, C1 symmetry (monomeric protein), C2 symmetry (dimeric protein). The proteins in this group are specialized in functions that require directionality or sidedness such as a formation of a hollow tube or chamber or interaction with membranes.The Dihedral Groups has higher symmetry i.e. it contains an additional perpendicular axis of two-fold symmetry.he proteins in this group are specialized in functions that require directionality or sidedness such as a formation of a hollow tube or chamber or interaction with membranes.
