| supercoiled plasmid | <molecular biology> The predominant in vivo form of plasmids, in which the plasmid is coiled around histone-like proteins. Supporting proteins are stripped away during extraction from the bacterial cell, causing the plasmid molecule to supercoil around itself in vitro. (19 Jan 1998) |
| supercoiling | <molecular biology> In circular DNA or closed loops of DNA, twisting of the DNA about its own axis changes the number of turns of the double helix. If twisting is in the opposite direction to the turns of the double helix, i.e. Anticlockwise, the DNA strands will either have to unwind or the whole structure will twist or supercoil termed negative supercoiling. If twisting is in the same direction as the helix, clockwise, which winds the DNA up more tightly, positive supercoiling is generated. DNA that shows no supercoiling is said to be relaxed Supercoiling in circular DNA can be detected by electrophoresis because supercoiled DNA migrates faster than relaxed DNA. Circular DNA is commonly negatively supercoiled and the DNA of eukaryotes largely exists as supercoils associated with protein in the nucleosome. The degree of supercoiling can be altered by topoisomerases. (19 Jan 1998) |
| superconception | <physiology> Superfetation. Source: Websters Dictionary (01 Mar 1998) |
| superconducting magnet | A magnet whose coils are cooled, usually with liquid helium, to a temperature at which the metal becomes superconducting, effectively removing all electrical resistance. (05 Mar 2000) |
| superconductor | <physics> A type of electrical conductor that permits a current to flow with zero resistance. Without superconducting coils, a toroidal magnetic-confinement fusion reactor would not be possible, because too much energy would be required to maintain the magnetic fields against resistive energy losses in the coil conductors.
