Question
Chapter 14.4, Problem 2MQ
Summary Introduction
The purple sulfur bacteria acquire its color from their accessory pigments and carotenoids. These pigments are involved in the light harvesting process. They are classified under the phylum Proteobacteria. These bacteria can convert or reduce sulfate as well as other sulfur containing compounds to hydrogen sulfide (gas) therefore, they are named as purple sulfur bacteria.

8. Transcription and Translation Practice: (Video 10-1 and 10-2)
A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense
DNA strand and label the 5' and 3' ends.
B. Use the antisense strand that you create in part A as a template to create the mRNA
transcript of the gene and label the 5' and 3' ends.
C. Translate the mRNA you produced in part B into the polypeptide sequence making sure
to follow all the rules of translation.
