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.
resonator. n. 1. (Electronics) any body or system that displays resonance, esp a tuned electrical circuit or a conducting cavity in which microwaves are generated by a resonant current.. resonator-a hollow chamber whose dimensions allow the resonant oscillation of electromagnetic or acoustic waves. cavity resonator, resonating chamber. chamber-a natural or artificial enclosed space. soundbox, body-a resonating chamber in a musical instrument (as the body of a violin).
