The core promoter region is located most proximally and contains the RNA polymerase binding site, TATA box, and transcription start site (TSS). RNA polymerase will bind to this core promoter region stably and transcription of the template strand can initiate. The TATA box is a DNA sequence (5'-TATAAA-3) within the core promoter region where general transcription factor proteins and histones can bind.
The color palette of diamond is very richly varied; it ranges from pink through red, blue, green, yellow and brown even to black diamonds. The rarest color occurring in natural diamonds is red, followed by green, blue, purple and brown.
Its size and color make it very unusual. When you think of the history of people mining diamonds, only one diamond has ever been found that has produced a dark-blue diamond the size and quality of the Hope Diamond. That gives you some sense of just how unusual and how remarkable it is.
