Are Viruses, Prions and Viriods Alive?

In order to see where computer viruses, viroids and prions fit into the scheme of life, we read 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 pick up a few of lifes properties because their survival depends on other support carrells. Life consists of living things and these living things permit carrells that buzz off the strength for order, reproduction, growth and development, vital force utilization, evolutionary adaptation, response to the environment and homeostasis (Campbell and Reece, 2002). These capabilities represent life in animals, plants and humans.All livings things are susceptible to unsoundness and disease, with viruses being a study cause; they also transmute 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 jail cells (cells that lack organelles), they share similar genetic materials and constantly wind (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, light upon into another cell and repeat the process. Viruses are also satisfactory of entering the cell and remaining vegetative (waiting for the rig ht environmental conditions to emerge), uni! te their viral deoxyribonucleic acid with the hosts DNA for replication or as a unchangeable cell fixture (Keeton and Gould, 1967), it doesnt necessarily slay the cell it enters (Norrby, 1981). There are two kinds of virus, which are found 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
