Crystals asymmetry and life
WebThe asymmetric unit is the smallest portion of a crystal structure to which symmetry operations can be applied in order to generate the complete unit cell (the crystal repeating unit). Symmetry operations most common to crystals of biological macromolecules are rotations, translations and screw axes (combinations of rotation and translation).
