How is a mutation in a bacterial cell that deletes three base pairs 10 base pairs upstream from the +1 site likely to affect transcription and why? See Section 17.1 (Page) .

Mutation in a Bacterial Cell

Explanation:

Bacteria comes under prokaryotes and its transcription starts at a specific site called promoterPromoters are specific sites on DNA where RNA polymerase binds and initiates transcriptionBacterial promoters are always present upstream to +1 transcription start sitePromoters are 70 base pairs long and contain 2 conserved sequences of 6 base pairs at -10 region and -35 region.-10 and -35 sequences are real sites where RNA polymerase binds and if  there is any mutation over there then transcription will be stopped or we can say can be terminated

The answer is option a
