Question

Arrrane these events:

Arrange the events taking place during eukaryotic transcription in order: The pre-mRNA undergoes processing to add a 5' cap and 3' poly-A tail, and to remove introns. RNA polymerase reaches the end of the transcription unit, copies polyadelynation sequence and then detaches from the DNA, releasing the pre-mRNA. RNA polymerase binds to the promoter. Transcription factors binds to the TATA box of the promoter. RNA polymerase initiates RNA synthesis at the transcription start point on the template strand. RNA polymerase moves downstream, unwinding DNA, and synthesizing RNA in a 5' rightarrow 3' direction.

Explanation / Answer

1. Transcription factors binds to the TATA box of the promoter

2. RNA polymerase binds to the promoter

3. RNA polymerase initiates RNA synthesis at the transcription start point on the template strand.

4. RNA polymerase moves downstream, unwinding DNA and synthesizing RNA in a 5'>3' direction.

5. RNA polymerase reached the end of the transcription unit, copies polyadenylation sequence and then detaches from the DNA, releasing the pre-mRNA.

6. The pre-mRNA undergoes processing to add a 5'cap and 3' poly-A tail, and to remove introns.
