Why Are Viruses Bad

1259 Words6 Pages

A virus is a very small and tiny non-cellular organism that can reproduce only by infecting a host cell. They are basically made up of genetic material and protein. This microorganism belongs to the family of viridae and genus of Virus. The term virus comes from the Latin word “virus” which means “poison”. In 1945, a scientist named Wendell Stanley discovered that viruses are made up of nucleic acids, protein and lips. Starting from that time, the study of virus became "Virology." These viruses are so tiny that it is measured in nanometer and they can only be seen in an electron microscope. Viruses are composed of a core of DNA or RNA surrounded by a protein coat. They can only reproduce by infecting living cells. The virus particles are 100 …show more content…

Viruses do not have the characteristics of a living thing. They have no energy metabolism and they do not reproduce independently. As a result, scientists considered viruses as a non-living thing. Viruses are not living things and they can’t to anything. On the other hand, after they enter a living cell, everything changes and they become living things. The viruses started to multiply or replicate themselves and spread bigger and bigger. There are two ways that virus replicate or multiply themselves. The first way is the Lytic cycle in which the virus attaches to a host cell and infuses the cell with its nucleic acid. The acid takes the host cell hostage. Then, the virus started to multiply with the nucleic acid and protein coat, producing a new virus. These new viruses continued the lytic cycle. Another cycle is called the Lysogenic cycle. The viruses entered the host cell, but they are slow in multiplying and it includes the HIV virus and herpes. While the viruses’ nucleic acid is present in the chromosome, it is not active so it doesn’t immediately affect the cell’s function. But then, it separates from the genetic material of the host cell and take over to multiply. The release of new viruses kills the host cell giving rise to the Lysogenic

These viruses include the following: herpes, measles, fowl pox, mumps, and equine encephalitis. It was said that Henrietta’s cells helped launch the field of virology. The book also mentions how viruses reproduce by injecting some of their genetic material into a living cell, essentially reprogramming the living cell so it reproduces the virus instead of itself which is a concept we have learned this semester (Skloot, Location

However, this determination is not always straightforward. Viruses have some, but not all, of the qualities of living organisms, and scientists have long argued whether or not they should be considered as living organisms. In this exercise you will determine whether specimens are non-living, living, or dead. CHARACTERISTICS OF LIFE - STATION LAB Lab Procedures: First, observe the specimens located at each station without touching it.

Dictionary.com defines a filo virus as “any of several filamentous single stranded RNA viruses.” The Hot Zone is a terrifying true story, by Richard Preston, about the historical stories of Ebola and other viruses such as Marburg and Simian Fever. Richard Preston teaches the reader that nature is unpredictable and that you should always be ready for something new. Dan Dalgard, Gene Johnson, and Nancy Jaax; these are just some of the extraordinary people who have made new breakthroughs in the medical field. Gene Johnson was one of the first discoverers of Ebola and has become an expert on the filo virus.

This field is analogous to epidemiology. It is geared more toward viruses specifically whereas epidemiology focus on diseases in general. It “is the study of viruses and virus-like agents, including (but not limited to) their taxonomy, disease-producing properties, cultivation and genetics” (Meštrović,2015). Medical professionals like Max Theiler go through a process to determine what kind of virus is being analyzed. They classify components of the virus so it was indistinguishable contagion.

In the articles, “The Deadliest Virus” by Michael Spector and “Out of the Wild” by David Quammen the viruses present can destroy the human race, but if the scientists can find a cure in time the virus can be stopped before they take over the world. These two articles have a lot of similar principles; however, the articles are different too. The authors use some of the same rhetorical patterns to develop their arguments, but they also use some unique to their own to take their arguments to the next level. The first article “The Deadliest Virus,” the virus H51N is discovered and explained.

Introduction In the book The Hot Zone by Richard Preston, Ebola is categorized as a filovirus. Filoviruses are becoming more and more common throughout the world and we do not know much about them. Most of these diseases are destructive and the victims normally do not survive. However, scientists must be confident that there is a cure for Ebola Viruses because their research has not yet ended.

The argument that all viruses are deadly is incorrect. In the Hot Zone, Preston explained how Ebola and Marburg caused an epidemic that killed over hundreds of people and animals. In the novel, Preston also mentions smallpox and malaria. Being diseases, there are cures for all of them which overtime will eventually prove to be not deadly. Although hundreds of lives were lost against the virus, there came a cure later on.

Later on the doctors also known as plague doctors tried to find ways to stop this horrible virus. They tried to let the victim bleed out and maybe it would drain the virus out of them, but this did not work. Because of it, it just spreads more than usual. Overtime the plague weakened, but that was not the end. It found a new way to spread, This name was called Airborne, how this worked was when someone coughed or sneezed, it would fly into another victim’s body.

Smallpox is a highly contagious and fatal disease that had a huge impact on the human population. It is thought to have been originated from India or Egypt at least 3,000 years ago. Smallpox is caused by two variations of the variola virus, variola major and variola minor. Variola major is the most common form of smallpox. It enters the body through the lungs and is carried to the internal organs.

Records of influenza symptoms date back thousands of years, with many massive outbreaks such as the 1918 Spanish flu and the 2009 Swine flu pandemic along the way. Scientists have been searching for a cure for years, but even through modern medicine, the fight against influenza continues. The structure, replication process, and limitations on modern medicine are just a few factors that keep influenza spreading across the world every year. Influenza is a special kind of microbe known as a virus. It is round and significantly smaller than its microbe counterparts such as bacteria, archaea, and eukaryota.
