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.
It is true that diamonds are extremely rare and precious. And it is true that diamonds are the hardest known natural substance, giving them durability for the ages. But it is their ability to dazzle the eye with brilliance and fire that makes diamonds the ultimate gemstone.
