In eukaryotic cells, transcription cannot begin until a. the two DNA strands have completely separated and exposed the promoter. b. several transcription factors have bound to the promoter. c. the 5′ caps are removed from the mRNA. d. the DNA introns are removed from the template.

Hi everyone here, we have a question asking why is it important to identify the promoter region first before the transcription process can start. A. It is where the RNA polymerase binds to the two so the reading of the basis can start. This is true and then the transcription process can start be. It provides the necessary enzyme needed for the transcription to perceive. This is incorrect. See it removes the cap that regulates the transcription process. This is incorrect. D it provides the template, which will serve as the pattern to be transcribed. This is incorrect. So our answer here is a it is where the RNA preliminary spines to, so the reading of the basis can start and then transcription can proceed. Thank you for watching. Bye!
