Biaxial nematic         
  • Biaxial nematic boomerang liquid crystal
  • Azo bent-core mesogen thermal transitions in °C: K 82.8 Sy 93.4 Sx 104.3 Sc 118.5 Nb 149 Nu 176.5 I
Biaxial nematic liquid crystal
A biaxial nematic is a spatially homogeneous liquid crystal with three distinct optical axes. This is to be contrasted to a simple nematic, which has a single preferred axis, around which the system is rotationally symmetric.

DNA supercoil         
  • Supercoiled structure of circular DNA molecules with low writhe. The helical nature of the DNA duplex is omitted for clarity.
  • Figure showing the various conformational changes which are observed in circular DNA at different pH.  At a pH of about 12 (alkaline), there is a dip in the sedimentation coefficient, followed by a relentless increase up to a pH of about 13, at which pH the structure converts into the mysterious "Form IV".
  • Stochastic, prokaryotic model of the dynamics of RNA production and transcription locking at the promoter region, due to PSB.
  • Drawing showing the difference between a circular DNA chromosome (a plasmid) with a secondary helical twist only, and one containing an additional tertiary superhelical twist superimposed on the secondary helical winding.
  • Supercoiled structure of linear DNA molecules with constrained ends. The helical nature of the DNA duplex is omitted for clarity.
  • Illustration of how cold shock affects the supercoiling state of the DNA, by blocking the activity of Gyrase. The signs ‘ − ’ and ‘+’ represent negative and positive supercoiling, respectively. Created with BioRender.com. Also shown is a stochastic model of gene expression during cold shock as a function of the global DNA supercoiling state. The transition from ON to OFF of the promoter (P) causes the locking of transcription (i.e. RNA production). When ON, the promoter can produce RNA, from which proteins can be produced. RNA and proteins are always subject to degradation or dilution due to cell division.

DNA supercoiling refers to the amount of twist in a particular DNA strand, which determines the amount of strain on it. A given strand may be "positively supercoiled" or "negatively supercoiled" (more or less tightly wound).

STN display

A super-twisted nematic (STN) display is a type of monochrome passive-matrix liquid crystal display (LCD).
