Summary Introduction

To determine:

The location of following diseases of common cold, diphtheria, coccidioidomycosis, influenza, pneumonia, scarlet fever, tuberculosis and whooping cough.

Concept introduction:

Respiratory system consists of two parts, lower and upper parts. Bacteria and virus affects both the parts but lower parts may affects highly than upper parts.

Microbiology: An Introduction, Chapter 24, Problem 1R

Respiratory system causes diseases which are affected by both bacteria and virus. The upper part causes disease like common cold, diphtheria and whooping cough. Common cold is a viral infection of the upper respiratory system. It is caused by rhinovirus and coronavirus. Scarlet fever caused by streptococcal exotoxin, affects the skin by reddening of tongue and peeling of affected skin. Diphtheria caused by Corynebacterium diphtheria, causes sore throat and swelling of neck. Whooping cough is another disease caused by Bordetella pertussis, tracheal cytotoxin. It affects the cilia and damages the respiratory passages.

Pneumonia causes lower respiratory infection and leads to same symptoms as cold, cough, headache and fatigue and so forth. Pneumonia is the disease of the lower respiratory system. Influenza is characterized by fever, chills, muscular aches and headache. Mycobacterium tuberculosis is a gram positive, rod and an obligate aerobe that causes tuberculosis. It is also a lower respiratory infection.

Conclusion

Many virus can enter into our respiratory system although there is a constant inhibition of pathogens by cilia and mucous membrane. Mostly the upper part is affected but only the lower part is affected by virus infection.

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
