WebDNA-binding domains on THRs have a high affinity for certain sequences of DNA called thyroid hormone response elements (TREs) and the resulting binding of the receptors to the DNA dictates the expression of linked genes. ... The GFP protein is naturally fluorescent and can be directly detected under ultraviolet light. The marker gene must be ... The common fluorescent lamp relies on fluorescence. Inside the glass tube is a partial vacuum and a small amount of mercury. An electric discharge in the tube causes the mercury atoms to emit mostly ultraviolet light. The tube is lined with a coating of a fluorescent material, called the phosphor, which absorbs ultraviolet light and re-emits visible light. Fluorescent lighting is more energy-eff…
