Are Viruses, Prions and Viriods Alive?

In order to see where viruses, viroids and prions fit into the scheme of life, we need to issue what life is and what the properties of life are. The capabilities of viruses, viroids and prions and the diseases they cause. Should they be considered alive if they only see to it a few of lifes properties because their survival depends on other dungeon carrells. Life consists of living things and these living things shoot carrells that harbor the s despatch for order, reproduction, growth and development, vital force utilization, evolutionary adaptation, response to the surround and homeostasis (Campbell and Reece, 2002). These capabilities represent life in animals, plants and humans.All livings things are susceptible to disorder and disease, with viruses being a study cause; they also misrepresent the behaviour of the host of whom they hold (Villarreal, 2004). The structure of viruses is of free particles that have a protein coat and a nucleic acid core (Keeton and Gould, 1967). Viruses have similarities to prokaryotic carrels (cells that lack organelles), they share similar genetic materials and constantly curl (Keeton and Gould, 1967) with each other. The particles float outside the cell, consequently enter a reasoned cell within the host. Once inside, the healthy cell manufactures new virus particles when the old virus provides the didactics (Keeton and Gould, 1967). The new particles leave the host cell, movement into another cell and repeat the process. Viruses are also equal to(p) of entering the cell and remaining vegetative (waiting for the right environmental conditions to emerge), combine their viral deoxyribonucleic acid with the hosts DNA for replication or as a unchangeable cell fixture (Keeton and Gould, 1967), it doesnt necessarily kill the cell it enters (Norrby, 1981). There are two kinds of virus, which are ground upon the kind of nucleic acid that makes up its genome... If you want to get a full essay, order it on ou! r website: OrderCustomPaper.com
