Symmetry in biology refers to the symmetry observed in organisms, including plants, animals, fungi, and bacteria. External symmetry can be easily seen by just looking at an organism. For example, the face of a human being has a plane of symmetry down its centre, or a pine cone displays a clear symmetrical spiral pattern.
Elements. The point group symmetry of a molecule is defined by the presence or absence of 5 types of symmetry element. Symmetry axis: an axis around which a rotation by. 360 ∘ n {\displaystyle {\tfrac {360^ {\circ }} {n}}} results in a molecule indistinguishable from the original. This is also called an n -fold rotational axis and abbreviated Cn.
Symmetry breaking and cortical rotation. Symmetry breaking in biology is the process by which uniformity is broken, or the number of points to view invariance are reduced, to generate a more structured and improbable state. [1] Symmetry breaking is the event where symmetry along a particular axis is lost to establish a polarity. Polarity is a ...
Chirality (chemistry) Two enantiomers of a generic amino acid that are chiral. (S)-Alanine (left) and (R)-alanine (right) in zwitterionic form at neutral pH. In chemistry, a molecule or ion is called chiral (/ ˈkaɪrəl /) if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes.
A palindromic sequence is a nucleic acid sequence in a double-stranded DNA or RNA molecule whereby reading in a certain direction (e.g. 5' to 3') on one strand is identical to the sequence in the same direction (e.g. 5' to 3') on the complementary strand. This definition of palindrome thus depends on complementary strands being palindromic of ...
Stereochemistry focuses on stereoisomers, red boxes in the picture. In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. [1][2] This contrasts with ...
Molecular geometry. Geometry of the water molecule with values for O-H bond length and for H-O-H bond angle between two bonds. Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other ...
Capsid. Schematic of a cytomegalovirus. Illustration of geometric model changing between two possible capsids. A similar change of size has been observed as the result of a single amino-acid mutation [1] A capsid is the protein shell of a virus, enclosing its genetic material. It consists of several oligomeric (repeating) structural subunits ...
