Options

  1. A5'- TA T A A T-3'
  2. B5'-T A A T A T-3'
  3. C5'-A A TA A T-3'
  4. D5'-A TA T TA-3'

Correct answer

A. 5'- TA T A A T-3'

Step-by-step solution

The promoters is bacterial and viral genes usually contains a consensus sequence of 5^ - TATAAT-3' forming RNA polymerase binding site or the Pribnow box, after its discoverer. Pribnow box lies with in the promoter about 10 base pairs before the starting point of transcription.
