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.
Diamonds can occur in nearly any color, though yellow and brown are by far the most common. The Yellow diamond is a member of the Carbon family and is the hardest substance known.
