During transcription holoenzyme RNA
polymerase binds to a DNA sequence and the
DNA assumes a saddle like structure at the point.
What is the sequence called ?
- ATATA box
- BGGTT box
- CCAAT box
- DAAAT box
View written solutionFree
Correct answer: A
After 25 bases from start of transcription point are TATA boxes. After 40 bases from TATA boxes appears CAAT boxes. Both of these sequences serve as recognition sites in eukaryotic promoters. Transcription in eukaryotic genes is a far more complicated process than in prokaryotes.
