For a common bacterial gene with a promoter. match each mutation to its most likely effect.

Map A Genetics: A Conceptual Approach 6th Edition Pierce MHE/Freeman For a common bacterial gene with a promoter, match each mutation to its most likely effect Increased rate of transcription Decreased rate of transcription No effect on transcription -36 down mutation -11 up mutation 20 mutation +1 mutation Exit E ePrevious @check Answer Ο Next Hint convention, bases in an RNA sequence are numbered relative to the start site. The start site is the first base the RNA transcript and is labeled +1. Sites upstream of the start site, including sites within the promoter, are assigned negative values

Answer

-11 up mutation: increased rate of transcription -36 down mutation: decreased rate of transcription -20 mutation: No effect on transcription

+1 mutation: No effect on transcription
