The lac-operon is actually a series of adjacent genes and regulatory elements in one small part of the E. coli circular chromosome. Lac-Operon components Definitions: P strands for promoter; it is the site where RNA polymerase attaches in order to transcribe mRNA.
The Surface Plasmon Resonance (SPR) technique is utilized to assess, in real-time, interactions between biomolecules, and in niche surface science applications.hotons are âabsorbedâ and converted to surface plasmons. Since the photons are not reflected, a âshadowâ occurs in the reflected light. Reichert Inc.âs Surface Plasmon Resonance instruments are optically configured to illuminate a spot on the gold surface over a range of angles from 58 to 85 degrees.
Best Answer: The resonator on a car is a hollow chamber in the exhaust tract. Its location is placed a certain distance from the muffler and engine to allow the resonant effect. This is to dampen parts of the noise coming from the engine and enhance other parts of it. Factory car makers tune the location of this resonator to tune the sound of your exhaust to better match the nature of your car ie sporty(loud) vs luxury(quiet) exhaust.
