RNA virus

Epstein - Barr virus or, Human herpesvirus 4, is the virus that causes infectious mononucleosis, and contains double-stranded DNA. This virus is species specific in that it only infects humans. The Epstein-Barr virus was discovered in 1964 when Michael Anthony Epstein and Yvonne Barr found it in a Burkitt lymphoma cell line. In 1968, they then linked the virus to the disease infectious mononucleosis. Once the host is infected with the virus it stays in the host for the remainder of the host’s…

Coronavirus comes from the family of coronaviridae, they are pathogens found in birds and mammals. Coronaviruses is a positive sense RNA virus and it was classified into four genera: Alphacoronavirus, Betacoronavirus, Gammacoronavirus, Betacoronavirus. There are many human types of the virus, for example, MERS-CoV, and SARS-CoV. SARS-CoV is a Severe acute respiratory syndrome. The Severe acute respiratory was found in 2003 when it first hit China and caused a big outbreak. Studies have shown…

John Watson and together they solved the structure of DNA using available X-ray data at the time and model building. After discovering the double helix model, Crick and fellow scientists were members of the informal "RNA tie club," which was created in order "to solve the riddle of RNA structure, and to understand the way it builds proteins." The club’s primary subject was on the "Central Dogma" which stated that DNA was…

GENE SILIENCING Gene silencing is something that most people do not know about. It is part of molecular biology which is things to with the natural body and life but to a minute size. Gene silencing was developed and still developing by the RNAi team at CSIRO in Australia which was led by a British-Australian virologist and geneticist named Peter Waterhouse. This team of a few also had significant contributions from Ming-Bo Wang who helped Peter Waterhouse develop this technique. This technique…

infective agents that are unable to support themselves and rely on other hosts for survival. Although they are not a living thing, viruses are able to infect humans, plants, bacterias etc. Depending on the type of virus, they target a specific organ or type of cells and inject their DNA or RNA in the cell to reorganize the genetic material of the cell. The cell then follows the new DNA instruction and produces more viral viruses. The adenoviridae, better known as adenoviruses, are a family of…

, 2010). A balance that is mutually beneficial to the hosts response mechanism and virus replication is essential, meaning that the pathogen…

A virus is a small infectious agent. There are different types of viruses. Viruses are all over the world and can be caused by many things and substances. Viruses are nonliving, it contains genetic information, has to survive (DNA/RNA) in a host, and can multiply from 1 virus to 1,000. Viruses have 3 components. Capsid surrounds DNA, Tail sheath-connected to capsid, and tail-fibers-connected to the sheath. The virus DNA travels down the tail sheath through the membrane. The virus tricks the cell…

For this assignment, the virus that I chose to research further was the rabies virus, from the genus Lyssavirus. The rabies virus is a single-stranded RNA virus with a cylindrical structure that is covered by a layer of matrix protein. Its lipoprotein envelope is scattered with rabies glycoprotein-carrying trimeric spikes. This glycoprotein envelope can also influence the rabies virus virulence. The article I read also covered the pathology of the rabies virus, prevention strategies, vaccines,…

their movement mechanisms. Class I is retro-transposons which use a RNA intermediate in transposition mechanism and Class II is DNA transposons remaining as DNA throughout transposition [4]. Retro transposons first transcribe themselves in RNA and then RNA is copied to DNA again by reverse transcriptase which is generally encoded by mobile elements. Copied DNA is inserted into target site. The main class of retro transposons are virus like and poly A retro transposons. On the other hand, the…

today I will be talking to you about the rabies virus. I will cover what rabies is, what organism causes this disease, and how it affects the body. I will also discuss the signs and symptoms, transmission, treatments or cure, and prevention of the rabies virus. What is rabies? Rabies is a type of zoonotic disease. A zoonotic disease is a disease that is transmitted by animals to humans. According to the Merian-Dictionary, the rabies virus is an acute virus disease of the nervous system of…
