Chronic liver disease is common among HIV-infected patients, and is increasingly a cause of mortality and morbidity. The disease is usually a result of the destruction and altering of specific liver cell membrane proteins, which damages and kills liver cells. How does HIV influence this activity? A. Protein synthesis is altered in HIV patients due to the insertion of viral RNA. B. Liver disease is a side-effect of several HIV medications. C. HIV halts DNA transcription and inhibits protein synthesis. D. Liver disease is caused by the attack of the HIV virus on the organ itself

Proteins

We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.  

Protein Expression

The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
