During transcription, the DNA site at which RNA polymerase binds is called as
Open in App
Solution
The correct option is A Promoter
- Transcription is when RNA is made from DNA. During transcription, RNA polymerase makes a copy of a gene from the DNA to mRNA as needed.
- 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, allowing it to bind to promoter DNA.
- RNA polymerase creates a transcription bubble, which separates the two strands of the DNA helix. This is done by breaking the hydrogen bonds between complementary DNA nucleotides.
- Then RNA polymerase moves towards the transcription start site.
So, the correct answer is option A.
