The HIV Envelope Virus and the Role of Nucleic Acid
Viruses are basically living biological organisms that cannot reproduce by themselves without a living host. Once contacting a suitable host cell, a virus enters into the host and takes over the functions of the host of a cellular membrane. It is in this manner that makes viruses the class of pathogen. They can cause infections in various parts of the body, as they invade the blood stream and get into the cells of the lymphatic system and the cell walls of the gastrointestinal tract etc. There are different types of viruses, like the herpes simplex one, and the hepatitis b, hepatitis c viruses.
These types of viruses are caused by a few specific species. The ones that cause infections in the body are broadly classified into four groups namely; herpes simplex, Epstein-Barr virus, herpes virus and hepatitis B virus. The herpes simplex one is the most commonly transmitted type of virus. This is also known as the cold virus and is responsible for around 75% of all viral infections. It can affect any part of the body and the signs are generally non-specific and similar to those produced by bacteria.
This is the type of virus that causes the common cold. Other well-known viruses are the herpes simplex virus and the Epstein-Barr virus. The herpes simplex one can affect the body’s soft tissue or the skin. On the other hand, the Epstein-Barr virus causes disease in the lining of the urinary bladder and on the surface of the skin.
The DNA of every living thing is replicated within the cells. When a living cell replicates it creates pairs of double-stranded DNA (DSC) molecules. These strands then carry genetic information telling the cell how to divide and reproduce. The proteins that make up DNA are put together using nucleic acid.
Nucleic acids are bases that combine with amino acids in order to form nucleic acid strands. There are many different types of DNA used in the replication process. The envelope is the DNA envelope of a virus that includes caps, sugars and viral RNAs that help it enter the cell membrane. The HIV envelope protein envelops HIV antigens that initiate activation of infected T-cells.
The HIV envelope protein coat is important because it helps protect T-cells from damaging the infected cell by triggering a reaction that damages the envelope protein coat. This allows the HIV virus to replicate uncontrollably through the body. This is why there is currently no known cure for HIV and some people infected with this virus do not show any symptoms.
