Summary Introduction

To determine:

The mode of transmission of tuberculosis in a population.

Introduction:

Tuberculosis is a potentially fatal disease caused by Mycobacterium tuberculosis which can infect almost every part of the body. It mainly infects the upper respiratory tract of the human body. The disease can be treated and cured with antibiotic and certain drugs.

Expert Solution
Check Mark

Explanation of Solution

The bacterium Mycobacterium tuberculosis causes tuberculosis and lungs are primarily infected by this bacterium. The TB bacteria can invade other parts of the body apart from lungs, such as spine and kidney. Not every person exposed to TB bacteria gets the infection. There are two major medical conditions associated with TB bacteria, TB disease, and latent TB infection.

In a population, the infection of tuberculosis is transmitted by respiratory droplets which contain mucus and droplets are transferred from the infected person to others through coughing.

Conclusion

In a population, tuberculosis is transmitted through respiratory droplets from the infected person.

The reason that homeless people are at risk for contracting tuberculosis

Expert Solution
Check Mark

Explanation of Solution

The reason that homeless people are at risk for contracting tuberculosis are given as follows:

1) Health care access is very limited to homeless people.

2) Misdiagnosis of tuberculosis with normal cold or pneumonia.

3) Homeless shelters are overcrowded which increases the transmission of disease through the respiratory droplet.

4) Tuberculosis is a bacterial disease which can be treated with antibiotics for several months, but the transient lifestyle of homeless people does not let them complete their antibiotics course.

Conclusion

Lack of healthcare facilities for the homeless people is the reason that they are more prone to tuberculosis.

Molecular Biology Please help with question. thank you You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold 6. Mutations in the promoter that prevent binding of RNA polymerase 7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase
Molecular Biology Please help and there is an attached image. Thank you. A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter. A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.
Molecular Biology Please help. Thank you. Discuss/define the following:(a) poly A polymerase (b) trans-splicing (c) operon
