This must be followed by promoter clearance, in order to move down the template and elongate the transcript. This requires the action of TFIIH. TFIIH is a multifunctional protein that has helicase activity (i.e., it is capable of opening up a DNA ... WebJan 1, 2013 · After initiation, Pol II must translocate from the core promoter region (promoter clearance), which is characterized by further unwinding of the DNA template and stabilization of the transcription bubble upon formation of at least a 6-bp DNA–RNA duplex [12,38,39]. After promoter clearance, Pol II often pauses in the promoter proximal region ...

Promoters are about 100-1000 base pairs long and are adjacent and typically upstream (5’) of the sense or coding strand of the transcribed gene. The coding strand is the DNA strand that encodes codons and whose sequence corresponds to the mRNA transcript produced. The antisense strand is referred to as the template strand or non ...
