DNA transcription. Illustration of the process of transcription of deoxyribonucleic acid (DNA,blue) to produce a complementary copy of ribonucleic acid (RNA,green). This is done by the enzyme RNA polymerase (grey). The RNA strand is constructed from fragments of ribonucleoside tri-phosphate (rNTP,T-shaped,lower right). This illustration shows the entry and exit channels (orange arrows) into the RNA polymerase structure. There are entry and exit channels for the DNA,an RNA exit channel,and an rNTP entry channel | |
