Concept explainers
(1)
To determine:
The bacterium that Person L was exposed to.
Case summary:
Person L takes a flight from Johannesburg to Atlanta. The woman who sat beside him was thin and huddles against the armrest. She was looking pale, tired, and often rubbed her chest as if it hurts. She was coughing loudly during the entire flight. Four weeks later, Person L received a letter from the State department of health and finds that he might have inhaled a deadly bacterium on that flight. He was advised to have a skin test to determine whether he is infected and also to wait for eight more weeks before being tested.
(2)
To determine:
The reason as to why Person L should wait for eight weeks before being tested.
Case summary:
Person L was exposed to Mycobacterium tuberculosis. Tubercular disease is characterized by cough, extensive lung damage, and blood-tinged sputum. The woman that sat beside Person L was having the signs of being infected with this bacterium. She was thin, coughing the whole way, had loss of appetite, and chest pain. So, he was exposed to Mycobacterium tuberculosis that causes tuberculosis.
(3)
To enlist:
The name of the skin test that Person L should have.
Case summary:
Person L was exposed to Mycobacterium tuberculosis. Tubercular disease is characterized by cough, extensive lung damage, and blood-tinged sputum. The woman that sat beside Person L was having the signs of being infected with this bacterium. She was thin, coughing the whole way, had loss of appetite, and chest pain. So, he was exposed to Mycobacterium tuberculosis that causes tuberculosis.
(4)
To determine:
The physician’s recommendation to confirm the test if the skin test is positive.
Case summary:

- Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forwardMolecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was successfully transcribed and translated, it produced a different protein than it produced in the eukaryotic cell. What is the most likely explanation?arrow_forward
