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) .
Bacteria comes under prokaryotes and its transcription starts at a specific site called promoter
Promoters are specific sites on DNA where RNA polymerase binds and initiates transcription
Bacterial promoters are always present upstream to +1 transcription start site
Promoters 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
