Question: Salmonella causes food poisoning and write full details about the bacteria?

The genetic code is (almost) universal, meaning that ribosomes from bacteria, fish, mice or humans will translate a particular open reading frame into identical proteins. However, it is not possible to place a message from bacteria into a human cell (or vice versa) and expect to see a protein produced. Why?

Describe the key properties of a signal sequence (or leader sequence or leader peptide). Explain the roles of these properties in guiding proteins across the cytoplasmic membrane. .

Describe stages in biofilm formation and explain how, at the molecular level, bacterial cells within the biofilm communicate with each other. .

How is light energy trapped by plants and used by the chloroplast membrane to generate ATP and NADPH?

Why do photosynthetic pigments only trap certain light wavelengths?

2. what are the difference between heterochromatin and euchromatin and how this influences gene expression?

3. how chromatin modifications can influence gene expression?

4. why start and stop codons are important?

5. how differential gene expression can lead to phenotypic differences in cells

People continue to take up smoking even though it has been known for over 40 year that smoking causes cancer and there is a warning on every pack of cigarettes. "Should lawsuits be thrown out against cigarette companies if the person took up smoking AFTER the warning was put on cigarette packs? Does free choice mean that society should not have to pay if that choice is known to cause cancer?

d) epinephrine

e) cortisone

I asked this question before and it did not get fully answered. Please do not answer if you cannot answer the whole question. It is only one question.

Bacteria can perform aerobic and anaerobic respiration depending on their enzymes and metabolic needs. A student argued that aerobic and anaerobic respiration should produce the same amount of ATP. He reasoned that they both use basically the same process; only the terminal electron acceptor is different. What is the primary error in this student’s argument? Think about the different organisms in the body and in nature. Discuss how some produce their energy by anaerobic and aerobic metabolism. Discuss what would be available to them in this environment and what would they use as a primary electron acceptor. Would they all produce the same amount of ATP (energy) ? Within your discussion, mention a specific bacteria that uses aerobic, or anaerobic, aerotolerant, facultative anaerobic metabolism etc. Include a link to your source not previously posted.   

please i want computer typing answer with details and explain

State the roles of proper food preparation and sanitation play in the decrease of microbial digestive tract infections.

What is the significance of capsule on particular strains of e.coli that causes digestive tract infections vs. strains of e.coli that cause urinary tract infections?

Create an experimental design to determine protein expression? Using high throughput or low through put.

Please explain in detail

In regard to guevedoce, why is it important that the parents are related and from the Dominican Republic? How is the disease inherited - mode of inheritance? (To describe the mode of inheritance, you have to determine if it is autosomal or X-linked and dominant or recessive.) Also would you expect the disease to be rare or common? Why?
