Chapter 8, Problem 4P

The diagram below shows a DNA duplex. The template strand is identified, as is the location of the $\text{+1}$ nucleotide.

$\text{+1}$

$\text{5'\_\_\_\_\_\_|\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_3'}$ template strand

$\text{3' \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ 5'}$ coding strand

1. Assume this region contains a gene transcribed in a bacterium. Identify the location of promoter consensus sequences and of the transcription termination sequence.

2. Assume this region contains a gene transcribed to form mRNA in a eukaryote. Identify the location of the most common promoter consensus sequences.

3. If this region is a eukaryotic gene transcribed by RNA polymerase III, where are the promoter consensus sequences located?
