Mysteries of the Virus :: essays research papers

Introduction to viruses For centuriessubmicroscopic organisms, also cognise as viruses,that puzzle and multiply at different rates inside of acell, contrive been circulating our planet.1 The cellproduces the various, essential components of thevirus. These components are 1) deoxyribonucleic acid or ribonucleic acidnucleic acids, which are the genes of the virus.Viral particles posses either DNA strands or RNAstrands, exactly never both in contrast bacterialinfections contain both. The metre of DNA/RNAin a virus changes depending on the slip of virus.2) A protein which is extremely important in ahazardous virus because is provides a strong,protective barrier as the virus passes from cell tocell.2 Viruses do not contain the enzymes andmetabolic pressures needed for self-duplication.The missing components are interpreted from the hostcells they infect. Replication begins when the virusenters the cell. The enzymes remove the coat ofthe virus, and the RNA or DNA particles come in contact with the ribo just abouts in the cell. The virus and then finds the protein by using the nucleic acid.Several new RNA or DNA strands are made.Once the cell has exceeded the maximum numberof strands, it then bursts dependent and the newparticles find new host cells. The process is thenrepeated.3 The avocation is a list of the many waysviruses rat be assort 1.) Whether viralparticles contain RNA or DNA strands. In somecases there are retroviruses. That is when a RNAvirus enters the cell, then converts to a DNA virus.2.) Whether the genome is integrity apart(p) ordouble stranded 3.) For single stranded RNAviruses, the code for a protein could be positivestranded or negative stranded. 4.) The genomemay be linear or tirade and may be in a singlesegment or multiple segments. 5.) The size andoverall shape of the virus. 6.) The effects of theviruses.4 Viruses can today cause damage to thecells by seizing the cells metabolic resourcesand/or by producing toxic components which interfere with their normal functions. These viruseswill generally make what is known as a cytopathiceffect (CPE) in tissue culture cells. Viruses canalso cause cells to alter their components makingthem targets for anti-cellular viruses such asAIDS.5 II. An In-Depth panorama Infectious diseasesare the third leading cause of death in the UnitedStates and the leading cause worldwide... but,we only spend 1% of our health-care reckon onprevention, claims Dr. David Satcher.6 For yearsscientists have been complaining about the amountof organization money spent on virus prevention.Within the past twenty years, more than 30 newvirulent types have been discovered, like LymeDisease, legionarys disease, AIDS, andEbola.7 For the past couple of years, scientists
