Are Viruses, Prions and Viriods Alive?

In order to see where computer viruses, viroids and prions fit into the scheme of life, we deal 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 a few of lifes properties because their survival depends on other hold carrells. Life consists of living things and these living things go carrells that bring in the ability 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 ailment and disease, with viruses being a study cause; they also transfer 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 prison cells (cells that lack organelles), they share similar genetic materials and constantly coil (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, dismiss into another cell and repeat the process. Viruses are also clear of entering the cell and remaining vegetative (waiting for the right environmental conditions to emerge), combining their viral deoxyribonucleic aci! d with the hosts DNA for replication or as a unchangeable cell fixture (Keeton and Gould, 1967), it doesnt necessarily decimate the cell it enters (Norrby, 1981). There are two kinds of virus, which are establish 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
