Are Viruses, Prions and Viriods Alive?

In order to see where computer viruses, viroids and prions fit into the scheme of life, we contract 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 revert a few of lifes properties because their survival depends on other sustenance carrells. Life consists of living things and these living things fork out carrells that defy the message for order, reproduction, growth and development, vital force utilization, evolutionary adaptation, response to the purlieu and homeostasis (Campbell and Reece, 2002). These capabilities represent life in animals, plants and humans.All livings things are susceptible to indisposition and disease, with viruses being a study cause; they also transform 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 cadres (cells that lack organelles), they share similar genetic materials and constantly twist (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, flow into another cell and repeat the process. Viruses are also adapted of entering the cell and remaining vegetative (waiting for the right environmen tal conditions to emerge), corporate trust t! heir viral deoxyribonucleic acid with the hosts DNA for replication or as a unchangeable cell fixture (Keeton and Gould, 1967), it doesnt necessarily eradicate 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 our website: OrderCustomPaper.com
