HIV Gene Function. GLYCOPROTEINS. For many years glycoproteins have been a subject of interest. However, it is in the second half of this century that they have aroused the interest of biochemists and biologists from a wide range of fields. This increased interest is partly due to the fact that glycoproteins were discovered to be abundant in living organisms. It is also due to the diverse functions of glycoproteins; glycoproteins appear in nearly every biological process studied. Many glycoproteins have structural functions. One of many instances is their role as a constituent of the cell wall. Glycoproteins also form connective tissues such as collagen. The diverse function of glycoproteins is a direct result of their structure. Controlling of glycoproteins is achieved through synthesis and degradation.
Structure Structurally, glycoproteins consist of a polypeptide covalently bonded to a carbohydrate moiety. The other class of glycoproteins are N-linked glycans. Function Enzymes: Glycoprotein enzymes are of three types. HIV and AIDS. How Can It Be Prevented? That person can then spread the virus to others through high-risk behaviors. HIV transmission can be prevented by: not having oral, vaginal, or anal sex (abstinence) always using latex condoms for all types of sexual intercourse avoiding contact with the bodily fluids through which HIV is transmitted never sharing needles How Do Doctors Test for and Treat HIV? Doctors now recommend that all people have at least one HIV test by the time they are teens. If you have questions about HIV and want to get tested, you can talk to your family doctor, pediatrician, adolescent doctor, or gynecologist. Clinics offer both anonymous testing (meaning the clinic doesn't know a person's name) and confidential testing (meaning they know who a person is but keep it private).
The HIV test can be either a blood test or a swab of the inside of your cheek. Reviewed by: Nadia Dowshen-Atanda, MD Date reviewed: February 2012. Basic Information about HIV and AIDS | Topics | CDC HIV/AIDS. HIV-1 Integrase. HIV-1 Reverse Transcriptase. Are Viruses Alive? Created by George Rice, Montana State University "Viruses straddle the definition of life. They lie somewhere between supra molecular complexes and very simple biological entities. Viruses contain some of the structures and exhibit some of the activities that are common to organic life, but they are missing many of the others.
In general, viruses are entirely composed of a single strand of genetic information encased within a protein capsule. Viruses lack most of the internal structure and machinery which characterize 'life', including the biosynthetic machinery that is necessary for reproduction. In order for a virus to replicate it must infect a suitable host cell". Artists conception of the T4 virus from Michael G. Background: When researchers first discovered agents that behaved like bacteria but were much smaller and caused diseases such as rabies and foot-and-mouth disease, it became the general view that viruses were biologically "alive. " "Viruses exist in two distinct states.
