The gene encoding a hormone necessary for insect development contains DNA binding sites for three gene regulatory proteins called A, B, and C. Because the binding sites for A and B overlap, A and B cannot bind simultaneously. You experimentally create a mutation in the binding sites for each of […]

Question 1. Which of the following patients who presented to a walk-in medical clinic is most likely to be diagnosed with a rhinosinusitis rather than a common cold? A man complaining of general fatigue, a headache, and facial pain with a temperature of 100.9°F A woman presenting with malaise, lethargy, […]

1. Describe an operon, the regulatory proteins, the cellular process and the molecules being “sensed”. 2. Include details about the orientation of the genes and the promoter/operator sequences or activator binding site. 3.Provide details about the repressor/activator and inducer/inhibitor proteins. 4. explain how the operon helps microbe survive and possibly […]

Q1. The chemical reactions involved in respiration are almost identical between prokaryotic and eukaryotic cells. In eukaryotic cells, ATP is synthesized primarily on inner membrane of the mitochondria. Where are the corresponding reactions likely to occur in prokaryotic respiration? Q2. Your body contains vast numbers of carbon atoms. How is […]
