E)transcription bead

Question

Quizplus · Accepted Answer

The single stranded region created by RNA polymerase during transcription is called a transcription bubble. This bubble forms because RNA polymerase separates the DNA double helix into two strands, and then reads one of the strands as a template for RNA synthesis. The bubble is about 18 base pairs wide and moves along the DNA as transcription proceeds.
