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.
Previous answer: 1,729 MHz. There is no resonant frequency of gold. Gold does have an NMR frequency, which is 1.729MHz. All NMR frequencies are dependent on the ambient magnetic field, and gold's 1.729MHz is valid for a magnetic field of 2.35 Teslas, which is 45,000 times stronger than a typical Earth field strength.
