Are Viruses, Prions and Viriods Alive?

In order to see where viruses, viroids and prions fit into the scheme of life, we pick out 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 command a few of lifes properties because their survival depends on other dungeon carrells. Life consists of living things and these living things bring in carrells that occupy the substance for order, reproduction, growth and development, vital force utilization, evolutionary adaptation, response to the milieu and homeostasis (Campbell and Reece, 2002). These capabilities represent life in animals, plants and humans.All livings things are susceptible to unwellness and disease, with viruses being a study cause; they also shorten 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 G ould, 1967). Viruses have similarities to prokaryotic jail cells (cells that lack organelles), they share similar genetic materials and constantly roll (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, exit into another cell and repeat the process. Viruses are also exposed of entering the cell and remaining vegetative (waiting for the right environmental condit ions to emerge), trust their viral deoxyri! bonucleic acid with the hosts DNA for replication or as a unchangeable cell fixture (Keeton and Gould, 1967), it doesnt necessarily polish 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
