The diagram below shows a DNA duplex. The template strand is identified, as is the location of the
Assume this region contains a gene transcribed in a bacterium. Identify the location of promoter consensus sequences and of the transcription termination sequence.
Assume this region contains a gene transcribed to form mRNA in a eukaryote. Identify the location of the most common promoter consensus sequences.
If this region is a eukaryotic gene transcribed by RNA polymerase III, where are the promoter consensus sequences located?
