31. Her identification of the space group for DNA crystals revealed to Crick that the two DNA strands were antiparallel . 32. The beta strands are within two antiparallel beta sheets that form an immunoglobulin-like beta-sandwich fold. 33. Hydrogen bonds allow for an antiparallel ?-sheet, which keeps the second and third loops roughly parallel. 34. The electron spins are characterized by two quantum mechanical states, one parallel and one antiparallel to B 0. 35. Applications of the GMR effect require dynamic switching between the parallel and antiparallel magnetization of the layers in a superlattice. 36. Spin antiparallel to their linear momentum ( likewise only right-handed anti-neutrino are found in nature ). 37. Structurally, it consists of a 12-stranded antiparallel beta-barrel with a convex and a flat side. 38. The caspase recruitment domain ( CARD ) is a protein module that consists of 6 or 7 antiparallel alpha helices. 39. You should use two LEDs in antiparallel or place an ordinary silicon diode in antiparallel with the LED, though. 40. You should use two LEDs in antiparallel or place an ordinary silicon diode in antiparallel with the LED, though.
