Extract of sample "Viruses"

Viruses Viruses are pieces of biological machinery that have no real consciousness of their own. They consist of some form of genetic material that is housed in a protein coat and is usually lined with protein receptors for attaching to hosts. In certain cases, viruses are responsible for keeping organism populations under control. In addition, viruses can be a mechanism for evolution. When viruses inject their genetic material into a host cell, the genes are integrated into the genome structure of the organism. Depending on whether the host cell enters the lytic or lysogenic cycle, the transfer of genetic material can either cause mutation within the virus or in the organism itself. Scientists had hypothesized that one of the ways in which the first cellular organisms developed was through the mutations that were spread by viruses. This is also how viruses are able to adapt and sometimes jump across species.
The HIV virus is a retrovirus meaning that it carries RNA instead of DNA. Once the RNA is injected into the host cell, the machinery begins to start manufacturing viral proteins and other RNA strands in order to replicate. First, the best way to prevent infection would be to give the cells the correct coding in order to prevent the virus from binding to the surface and passing through the membrane. If the virus was able to pass through the membrane, the next line of defense would be to prevent translation from occurring in order to prevent the viral proteins from assembling and replicating. This means inhibiting enzymes such as RNA polymerase and other protein-assisting enzymes. The only way for this to be accomplished would be through advanced genetic sequencing or through molecular restructuring of the immune system to counteract the binding effects of the proteins.

Viruses, Mononucleosis, Immune system

...?Viruses, Mononucleosis, and Immune System Viruses Viruses are tiny bits of genetic material wrapped in a protective protein coat and is considered as the simplest living things on Earth. It is also known as the ultimate parasites and depends primarily on the host (Goldstein, 4). The structure of viruses has particles called virions and is constructed with helical symmetry containing only one protein or very few proteins (Strauss & Strauss, 36). Viruses that are simple and regular in structure often crystallize which have made them suitable for X-ray diffraction. Unlike all living things, viruses are not cells. They are called parasites...

...? Viruses Viruses are living organisms that are smaller than bacteria and are generally responsible for a number of infectious diseases and even life threatening diseases. They have the ability to replicate themselves within the human cell and this process of reproduction takes place at a very fast rate and therefore diseases caused by viruses gain strength quickly. Viruses are the tiniest of organisms and yet they have the power and strength to attack all other organisms including human, animals, plants, bacteria, etc. The viruses are almost hundred times smaller than a bacteria cell which themselves are quite tiny. There are millions of types of...

Are viruses alive

...? Are viruses alive? Introduction Viruses are microscopic agents that survive only in the nucleus of cells of other living organisms. This implies that viruses live in any living thing both plants and animals. They replicate inside the cells and, in some advanced cases, they feed on the nucleus of the cells thus resulting in the death of the cells. Viruses have unspecified structure of deoxyribonucleic acid commonly referred to as the DNA (Dilcher, 2000). The DNA defines the structure of cells, the fact that viruses have indefinite DNAs makes them capable of changing their structure from time to time thus making it difficult for the body cells to identify...

Viruses are living organisms

...VIRUSES ARE LIVING ORGANISMS Viruses are living organisms or not This has been a major topic of debate for decades now because while some argue thatviruses are alive, others contradict this claim on the basis on how we define life. We believe something is alive when it displays the following characteristics: Breathes Shows irritability Grows Move Reproduce With Viruses however, we find that they do not display 4 of the 5 characteristics of living organisms but most definitely reproduce and can adapt to their environment. Does that mean they are alive This is a million dollar question and the answer is rather complex. Viruses are not as alive as bacteria because bacteria...

Emerging Viruses

...Order 239492 EMERGING VIRUSES: NOT ALIVE, BUT POTENTIALLY FATAL Introduction Up-and-coming strains of animal viruses are more lethal despite thefact that these microscopic things are non-living and acellular (Engelkirk and Burton, 2007). Practically, increased virulence and pathogenicity of new viruses can be ascribed to their expressed characteristics called phenotypes. These new phenotypes are actually the end result of their evolved genetic material, which is either one of the two nucleic acids, DNA or RNA (Engelkirk and Burton, 2007). There could only be one usual reason for the evolution of viruses DNA or RNA akin to evolution of other living things. Obviously,...

Viruses And Cancer

...VIRUSES AND CANCER By Janice Wotherspoon, BSW Submitted November 23, 2005 Section: Semester: Year: The purpose of this report is to examine information about the link several prominent researchers have found to exist between viruses and cancer. According to the evidence found by researching the internet it appears there is a definite need for women to be cognizant of the risks for developing cervical cancer if they are exposed to specific viruses. Details of research conducted by Darron R. Brown and colleagues from the Indiana University School of Medicine(1) and a series of collaborative studies between Drs. James McDougall, Janet Daling, Steve Schwartz, Peggy Porter, and Denise...

What are computer viruses

...The operating system within any computer is the most important software because it is the software that provides the computer with the interface to inter act with the outside world. Specifically speaking what it does is that it connects the computer with the hardware, the mouse, the keyboard, speakers, monitor and other such hardware devices are connected and recognized by the computer only because they have been connected to the operating system. The operating system uses ‘drivers’ to interact with these hardware devices, that is why when you install a new hardware device the computer asks for the drivers CD. The operating system basically creates an environment in which the application programs can function. Operating system... operating...

Spyware and Viruses

...Spyware and Viruses Introduction Spyware is kind of malware, which is installed on a computer without approval or awareness of the owner with the aim of gathering the private information of the owner. It is usually hidden such that the user can not know about it, and collects information regarding the internet interaction, any important information, passwords and keystrokes (Parikka, 2007). In addition, they can affect the performance of a computer negatively by the installation of more software, which redirects the web browser searchers, reducing the speeds of connections, changing settings of computer, disrupting the ability of network connection completely or even changing the homepage. Moreover, it can be used as a...

Polymorphic Viruses

...Polymorphic Viruses The contemporary society has numerous innovations, which include computer science and information technology. This paper examines the concept of polymorphic viruses in computer science. In particular, the paper offers a summary, which depicts a personal impression on an article called, The Molecular Virology of Lexotan32 (Orr 2007). Finally, the application of the article to Root kits is evident in the paper. There is an evident replacement of instructions in order to monitor the growth of the code in the consequent regenerations. The growth of the code presents numerous challenges since one cannot control the insertion of irrelevant instructions. Therefore, it is remarkable to note...
