A coiled coil is a structural motif in proteins in which 2–7 alpha-helices are coiled together like the strands of a rope. (Dimers and trimers are the most common types.) Many coiled coil-type proteins are involved in important biological functions, such as the regulation of gene expression — e.g., transcription factors. Notable examples are the oncoproteins c-Fos and c-jun, as well as the muscle protein tropomyosin.
my uncle was describing something that showed light traveling at a slow speed and i had no idea how it worked. he said it was a clear solid plastic like tube wrapped around in a coil and when you shined a light in one end you could watch it enter the coil, spin around the coil, and then exit...
if we were to insert a search coil inside a solenoid, (plane of coil perpendicular to B), would the induced current change direction in the middle of the solenoid ? it would have to wouldn't it since it would now be approching the opposite pole ---
