MCQ
During transcription, the DNA site at which RNA polymerase binds is called as:
- APromoter
- BRegulator
- CReceptor
- DEnhancer
Explanation:
Transcription is the process of RNA formation from DNA.
During transcription, RNA polymerase makes a copy of a gene from the DNA to mRNA.
During transcription, the DNA site at which RNA polymerase binds is called a promoter.
Transcription begins with binding of sigma factor proteins to the RNA polymerase holoenzyme, thus, allowing it to bind to promoter DNA.
RNA polymerase creates a transcription bubble, which separates the two strands of the DNA helix.
Then RNA polymerase moves towards the transcription start site for the process of transcription.
