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.
Only one in every 10,000 diamonds possesses natural color and is referred to as a colored diamond. For this reason, colored diamonds are purchased almost exclusively for the intensity and distribution of the diamond's color.olored diamonds are primarily cut to emphasize their color. This contrasts with colorless diamonds that are cut to maximize sparkle or brilliance, which in some instances can detract from the natural color of a colored diamond.
