The Ebola is a virus, an infective agent which typically consists of a protein coat that contains nucleic acid, and multiples within a host’s living cells. A Virus cannot be seen by a light microscopy due to its small size. The Ebola virus is a member of the Flioviridae family, which contain single, linear, negative-sense ssRNA (ss meaning single strand) genomes that house the cells genetic material. The tubular Ebola virions are normally 80 nm in diameter and 800 nm long. In the center is the necleocapsid

These characteristics are Reproduction, Growth and Development, Cells, DNA, Energy, Adapt/Evolve, and finally Homeostasis. Every virus has one or more of these traits. First we have reproduction, reproduction is a very big deal with viruses, as viruses relate to it. For example, the Polio Virus, this virus is very deadly, not only to us, but to our environment. This virus spreads and becomes stronger by the minute, as it is doing this, it uses energy, now once it spreads, it doesn't stop, it multiplies

How would one feel like if they helped in many of charities like the UNICEF Foundation who funds the ENOUGH project, or even came up with their own charity? “I am supporting the Lupus Research Alliance because they are getting results, and thats what gives people with lupus the most hope.” (BrainyQuote). People have hope now because Selena is helping scientists with coming up with a cure for Lupus. She is letting them experiment on her and do test results to see what the differences are with-in time

influenza virus. There are many subtypes of influenza viruses due to the fast mutating nature of this type of virus; these subtypes are categorized by the Haemagglutinin (H) and Neuraminidase (N) antigens on the surface of the viruses (USDA 2015). Avian influenza virus is a zoonotic pathogen, meaning it can be passed from animals to humans, causing infection. Birds are the primary host for avian influenza viruses and they don’t usually infect humans (CDC 2017). Birds carrying the virus shed it in

Gene therapy is deemed to be the ‘use of genes as medicine’. “Gene therapy is a form of therapy that involves inserting one or more corrective genes that have been designed in the laboratory, into the genetic material of a patient's cells to cure a genetic disease by replacing the missing or malfunctioning genes” (Mandal). There are two types of gene therapy, which are in vitro gene therapy, which takes place outside the body and in vivo therapy, which takes place inside the body. Both types are

Although the technology of heart gene therapy is at its initial stages and only medical trials have begun, some ethical questions and arguments are arising on its acceptability to be used for treating people. Heart gene therapy involves insertion of a foreign gene and this is argued to be against nature because our natural genetic makeup is altered from this treatment (Kelly, 2007). This has erupted discussions for and against this treatment. Some people argue that altering our genetic makeup, even

Introduction Potato virus X (PVX) is a plant RNA virus. Its infection cycle includes invasion of the host plant, RNA replication, translation of viral proteins, cell-to-cell movement and release of new virions. Upon infection, PVX releases its plus-strand RNA genome from the virion and produces a viral replicase using host translation machinery. The replicase synthesizes minus-strand RNA. Subsequently new plus-strand genomic RNA (gRNA) and subgenomic RNAs (sgRNAs) are produced. Movement and coat

p. 715, 2013). Acute pharyngitis can be caused by both virus and bacteria microorganisms. About 40 to 60% of acute pharyngitis is of a viral origin (Burns et al., 2013). Adenovirus is the most common virus associated with acute pharyngitis. Although, there are other associated viruses, which includes Epstein-Barr virus (EBV), cytomegalovirus, influenza virus, parainfluenza, herpes simplex virus, enterovirus, and human immunodeficiency virus (Burns et al., 2013). There are some common bacterial organisms

certain or several species, while others is capable of infecting many. The range of different types of cells that a virus could infect is regarded as its host range. Plant viruses has a narrower host range such that they only replicate in living plant cells and fails to infect animal cells. [3] On the other hand, while some animal viruses are known to be species-specific, such as smallpox virus that could only infect humans; there are also viruses that has a board host

that helps the virus attach to and penetrate the host cell. In some cases, certain viruses have a membrane surrounding the capsid, called an envelope. This structure allows viruses to become more stealthy and protected. There are two cycles in which a virus can go into: lytic and lysogenic. The lytic cycle consists of the virus attaching to a cell, injecting its DNA, and creating more viruses, which proceed to destroy the host. On the other hand, the lysogenic cycle includes the virus attaching to
