Viruses

Describe the structure and function of bacteria in comparison to a virus Both bacteria and viruses are mircoogranmisms. Viruses are small obligate intracellular parasites, which by definition contain either a RNA or DNA genome surrounded by a protective, virus-coded protein coat called a caspid. They are classed as non-living because they cannot surive on their own. Conversley, bacteria are single celled livng microbes. The cell structure is simpler than that of other organisms as there is no…

According to website cloud tweaks, about $4.55 Billion U.S. dollars are spend in a U.S. house-holds per year from viruses, spyware and other malware ("Cloud Infographic”, 2014). All of money is wasted due to the lack of security. When thinking about security, the first thing that comes to mind is passwords. Many things today are password protected in order to keep protection for personal belongings. This can range from protecting Facebook conversation chats to protecting online bank account…

Scientific concept Spread of viruses To understand how vaccines are helpful in protecting us from the harmful effects of vaccines, we must first learn what viruses do to the human body. Viruses cannot survive alone, they need a host body to carry out basic functions. After entering a body they hook onto a host cell and insert their genetic material into it, gaining control over the cell. They then proceed to replicate rapidly before violently spilling from the cell and spreading to…

since the study of virology began, is whether or not viruses should be classified as a living organism or not. Living things are highly organized, and have may other characteristics that accompany it. The general agreement among scientists is that there are seven main characteristics of life; cellular organization, metabolism and energy use, response to stimuli, regulation and homeostasis, growth and development, evolution, and reproduction. Viruses share many of these characteristics, while…

of a host. For centuries scientists have debated the topic of whether viruses are living organisms- or not. Viruses have been left in a “gray area”, becoming ignored in the study of evolution by scientists. When not in contact with a host, viruses tend to stray from the characteristics that define life. Characteristics such as the ability to respond to their environment, lack of cells, and the ability to reproduce. Viruses contain great potential once inside of a host. They thrive,…

Viruses are miniscule organisms which are too small to be seen with a normal microscope. Invented in the 1940s, the electron microscope allowed scientists to see that a virus is nothing more than a core of genetic material (RNA or DNA), concealed in a protective protein coat. The tiny agents of disease are not referred to as living things, due to the fact that they cannot replicate on their own. They must attack the cells of another living organism and take over the cells' machinery to then make…

even today. The virus has evaded classification for years, baffling scientists and the common man. Though it was difficult to conclude, it can be said that viruses are in fact non living. This can be deduced due to the virus only adhering to some of the necessary characteristics that an organism needs to be considered alive. First of all, viruses do not seem to be a cell or made up of cells, which is a very vital characteristic of life. They do contain DNA but do not contain a cytoplasm or…

A very widely debated scientific dilemma that has been going on for years is whether or not viruses are alive. Although viruses do have a few characteristics of life, they do not have all of them, and they especially don’t have the most important ones. Throughout the case study there were great arguments for either side, and although it was a tough decision, I do not believe that viruses are alive. Viruses cannot metabolize energy and they are not made up of cells. One characteristic of life is…

they are isolated. The reason behind that is because viruses and prions need a host to reproduce. Bacteria are single celled microbes. The cell is simpler than other organisms because there is no nucleus or membrane bound organelle. Bacteria’s genetic information is contained in a single loop of DNA. They reproduce by binary fission in which the single cell divides into two identical daughter cells. It is a continuous debate whether viruses are living and non-living. They can infect any animal…

patient had finished her first year of college. It began with a reduction of eyesight and moved to the loss of cognitive functions. Slow viruses also know as Lentivirus are different from regular viruses due to the less aggressive nature of the infections. Unlike a normal virus that quickly attacks the body and can bring about death on a rapid pace slow viruses take their time. They generally take a long time to manifest symptoms. The problem with this is that by the time symptoms become…
