Right-handed double-helix ultrashort DNA yields chiral nematic phases with both right- and left-handed director twist.
Concentrated solutions of duplex-forming DNA oligomers organize into various mesophases among which is the nematic (N(∗)), which exhibits a macroscopic chiral helical precession of molecular orientation because of the chirality of the DNA molecule. Using a quantitative analysis of the transmission spectra in polarized optical microscopy, we have determined the handedness and pitch of this chira...
متن کاملCharacterization of right-handed and left-handed shapes
Many natural shapes are chiral (or handed). Our hands, for example, have a righthand version and a left-hand version, the two types being mirror images of each other. Molecules are also classi ed according to their chirality, which determines their chemical characteristics. Glucose, for example, is sweet only in one chirality, while it is tasteless in the other. The notion of chirality for two ...

متن کاملEuclidean general relativity from “ left - handed area = right - handed area ”
A classical continuum theory corresponding to Barrett and Crane’s model of Euclidean quantum gravity is presented. The fields in this classical theory are those of SO(4) BF theory, a simple topological theory of an so(4) valued 2-form field, B μν , and an so(4) connection. The left handed (self-dual) and right handed (anti-self-dual) components of B define a left handed and a, generally distinc...
