Virus and Bacteria Virus - A virus is a capsule of protein that contains genetic material. A virus cannot reproduce on its own; it must infect a living cell to grow. Bacteria - Bacteria are one-celled organisms that live on their own. They can multiply and reproduce by subdivision Bacteria and viruses cause many of the diseases we are familiar with and may sound synonymous; they are greatly different from each other. [pic] o They differ greatly in size. The biggest viruses are only as large

MANIPULATION OF BACTERIA INTRODUCTION: In this experiment that we performed‚ there were many methods that were used to help us manipulate and identify the bacteria E.coli on a MacConkey agar plate. The first part of the experiment involved the methods of manipulating‚ identifying and counting the bacteria and the second part was to find out whether the bacteria E.coli was the only type found in the given area by gram staining. E.coli was the chosen bacteria for this type of experiment. It is

a. The bacteria that causes botulism are found in soil‚ water‚ animal guts and dung. When the spores exposed to low oxygen and certain temperature‚ they produce botulinum toxin‚ able to germinate‚ metabolize‚ food sources through an aerobic respiration to produce toxin. The toxin blocks the release of acetylcholine from motor nerve endings causing paralysis symptoms. The botulism either food born‚ eating contaminated home-canned foods where the fermentation takes place. or through abrasion in the

Aim How temperature affects membranes: investigating the effect temperature has on Beta vulgaris membranes when submerged in a range of different temperatures for one minute. Background Information A cell membrane is made up of a phospholipid bilayer formed by phospholipids that have a hydrophilic head and a hydrophobic tail. The phospholipids arrange themselves in order that the heads are exposed to water and the tails are not thus forming the bilayer. When the temperature increases molecules

a universal method of identifying bacteria allows for all scientists from any part of the world to identify the same species in an identical manner allowing for a precise of classification. Bacteria are distributed throughout the world in almost every conceivable habit. Bacteria are unicellular microorganisms‚ with variable shapes and nutritional needs. They lack a distinct nucleus and occur singly or in chains or clusters and form distinct colonies. Bacteria are classified on the basis of many

Bacteria are among the oldest species in the world.They both incerease in number and comply with nature very quikly so‚they maintain their species.Therefore‚bacteria have been the most common type of species according to number.Hence‚bacteria had been classified in order to make analysis.easily.Bacteria can be classified into three main categories on the basis of their nurition:saprophytic‚parasitic and chemoautotrophic bacteria. The Saprophytic bacteria are the first type of bacteria

Having the ability to collect and identify unknown microorganisms is vital in health and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study

Bacteria and Archaea The Archaea are presently recognized as one of the two main domains of prokaryotes. The majority of genes that indicate Archaea to be different from Bacteria are for information transfer processes such as DNA replication‚ transcription and translation. Of these‚ DNA replication machinery appears to be most different between the two domains. In terms of transcription‚ the core subunits of the RNA polymerase are the same in Bacteria and Archaea‚ but archaea also contains several
