The virus genome covered by the capsid penetrates the host cell. Once inside, the virus is uncoated as the envelope and capsid are removed. Free of its covering, the viral genome (DNA or RNA) proceeds with biosynthesis. Newly assembled viral particles are released by budding. Components of viral envelopes (i.e., lipids, proteins, and carbohydrates) are obtained from the plasma or nuclear membrane as the viruses leave the cell. Budding
Environmental Hazards What are toxicants and how do they affect living organisms? According to Dr. Celine Godard, toxicants and toxins both reference substances that are toxic; however, toxins are made in nature (like in poisonous mushrooms or in the poisonous venom that snakes use to kill their prey) and toxicants are human made (Godard, et al., 2001). Examples of toxicants would be "industrial waste products and pesticides" -- along with pollutants that
Bacteria? Many people believe that bacteria only cause disease and death. This is not technically true. While we have all suffered from some kind of an infection which we are told is caused some noxious form of bacteria, this is just a small part of what bacteria contribute to out lives. First, it would be well to add a bit of science to be clear about what bacteria are. Defined most
Bacteria Effect of date extract on different types of bacteria Taxonomy of date Kingdom: Plantae Division: Magnoliophyta Liliopsida Order: Arecales Family: Arecaceae Genus: Phoenix Species: Phoenix dactylifera Binomial mane: Phoenix dactylifera Linn (Bostoen 2005) Botanical Descriptions The date palm is known in technical terms by its botanical name Phoenix dactylifera. The properties and the composition of the date extract have been noted to have many beneficial effects in medicine as well as domestically. The following paper intends to shed light on the impact
human papilloma virus and the description of epidemiology as it relates to the virus. Steps and methods of epidemiology have been discussed in detail alongside statistical data for demographics taken from surveillance records. Moreover, research data have been taken as vital assistance to compliment the study of this research paper and to prove results with evidences from researches (Duncan, 1988). Statistics have been taken from World Health Organization for the
Gram Stain Bacteria Identification Following standard procedure for Gram staining, a slide was prepared by heat fixing the sample and applying the primary crystal violet stain (Bruckner, 2012). After incubation in the primary stain for a period of one minute, the stain was rinsed under a slow stream of water for four seconds before fixing the remaining dye with Gram's iodine, with immersion in this mordant lasting one minute (Bruckner, 2012).
