The defining property of a crystal is its inherent symmetry. Performing certain symmetry operations on the crystal lattice leaves it unchanged. All crystals have translational symmetry in three directions, but some have other symmetry elements as well. For example, rotating the crystal 180° about a certain axis may result in an atomic configuration that is identical to the original configuration; the crystal has twofold rotational symmetry about this axis. In addition to r… WebApr 7, 2024 · The 5′CLs are one of the most conserved RNA elements among enteroviruses (b) The three-dimensional consensus fold of the 5′CLs in enteroviral …
