What is the basic structure of the HIV virus? What is the function of the glycoproteins in its envelope?
Homework Answers
HIV is an RNA virus. In its middle there are strands of RNA and opposite transcriptase molecules. The middle is blanketed by means of a capsid, a layer of proteins. The capsid then is protected through an envelope having glycoproteins and lipids.
The glycoproteins of the HIV envelope are located at the outer surface of the virus and they're answerable for the popularity of the cells to be infected (the HIV host cellular is the CD4 lymphocyte) and for the adhesion of the virus to the mobile membrane. (CD4 is a receptor glycoprotein of the outer membrane of a few lymphocytes).

You are helping design a new electron microscope to investigate the structure of the HIV virus. A new device to position the electron beam consists of a charged conducting ring with a gap - i.e. an incomplete ring - as shown in the figure below. The electron beam will pass through the center of the ring traveling perpendicular to the ring (into the page here). To complete the design, your job is to calculate the electric field in the center...

1.) Once in the respiratory tract, the flu virus targets cells based on specific glycoproteins on their surfaces. How does the virus gain entry into the target cell? Multiple Choice a.)Glycoproteins within the virus structure bind with glycoproteins on the membrane of the target cell and the virus squeezes through the glycoprotein into the cell. b.)Viruses are made up of lipids and can therefore diffuse through the membrane of target cells, gaining entry. c.)The H spikes of the influenza virus...

Determine whether the structure, location, and functions describe proteoglycans, peptidoglycan, glycoproteins, or glycolipids. GlcNAc is N-acetylglucosamine; MurNAc is N-acetylmuramic acid. Proteoglycans Peptidoglycan Glycoproteins Glycolipids Structure Location part of proteins at outer surface of plasma membrane, in extracellular matrix, and in blood Functions many functions, including cell adhesion strength for cell envelope Answer Bank glycosaminoglycan covalently joined to a protein at a Ser residue many functions, including acting as hormones bacterial cell wall extracellular matrix; some are integral membrane proteins outer...

Elisa Test The standard test for the HIV virus is the Elisa test, which tests for the presence of HIV antibodies. If an individual does not have the HIV virus, the test will come back negative for the presence of HIV antibodies 99.8% of the time and will come back positive for the presence of HIV antibodies 0.2% of the time (a false positive). If an individual has the HIV virus, the test will come back positive 99.8% of the...

AIDS is caused by the virus HIV. A key enzyme in the HIV life cycle is reverse transcriptase (RT) RT is used by the virus HIV to copy its genes. RT takes RNA nucleotides and attaches them together into a polymer to form the virus' RNA genome. Water is produced during this reaction. Use the following information to answer the questions below. The type of chemistry that RT is doing is most likely to be hydrolysis A common treatment for...
