Investigators have found a new species bacteria that lives under both aerobic and anaerobic conditions.They hypothesize that different genes are expressed in each condition.What experiment could test this hypothesis and identify important genes?

Question

Quizplus · Accepted Answer

Collecting mRNA from both anaerobic and aerobic conditions and generating two cDNA libraries would allow for a comparison of gene expression in each condition. This would identify important genes that are expressed in each condition and may provide a better understanding of the bacteria's ability to survive under different oxygen conditions. Completely sequencing the genome, measuring levels of RNA polymerase, and designing primers to sequence a specific region of the genome would also provide valuable information but may not specifically address the hypothesis being tested.
