...Bacterium capsule Collage Introduction Bacterium capsule is a protective structure surrounding some bacterial. It is attached to the cell wall through phospholipids. It promotes bacteria adhesion to surfaces. It also acts as a permeability barrier and as a defense mechanism against phagocytosis and desiccation (Barton, 2005). The bacterium capsule gets through a series of external openings (spiracles) which acts as a muscular valve. Then it gets through the internal respiratory system, a densely networked array (the tracheae). This network of transverse and longitudinal tracheae in the menduca larva equalizes pressure throughout the system. Since it is a layer that lies outside the cell wall... ...

Biology Despite the claims that Edward Jenner is the greatest microbiologist of all time due to his contribution in the improvementof human health, I tend to oppose this view on the grounds that there are other renowned personalities, whose contribution in the field of human health remains unsurpassed. As a matter of fact, it is purported that Jenner was not the first person to suggest the relationship between immunity and smallpox. Louis Pasteur In my opinion, one of the important personalities, who have made a great...

...bacterium method: Plants naturally contain a transformation mechanism in the form of a bacterium. In this mechanism the contact of this bacterium with a cell results in its integration into the chromosomes. Scientist exploit this natural tendency to create resistances... What is meant by the term genetic engineering? The process involves the recombination of DNA for scientific purposes and is termed as Genetic Engineering. This mainly includes the alteration of gene information inside cells to achieve desired results. Genes are present within a living cell in the form of DNA. They are actually strands of amino acids containing a code of life that exhibits the properties and behavior of a living...

...bacterium in MSU 6 is more susceptible to ampicillin than gentamycin. It can therefore be inferred that the bacterium in MSU 6 is more resilient than that in MSU 4. Again, MSU 2 does not appear as the test was not carried out. Staphylococcus species do not produce beta... ?Microbiology report First Sur Registration number Introduction Definition of terms and abbreviations: DST-diagnostic sensitivity test, MSU-mid stream urine, Antibiotic-this is a chemical agent that kills or inhibits bacterial growth.

...Bacterium Agrobacterium has the capacity to infect plants hence has been used as an appropriate DNA carrier. Its preparation would be conducted in a specialised solution that would make its cell walls even more porous. The desired gene would then be inserted into the plasmid of the bacterium – its extra chromosomal DNA molecule – and then dropped into the solution which would be heated to allow the plasmid to enter into the bacterium and express a new gene. The altered... Genetically Modified Crops Introduction The blueprint in the bodies of living organisms controlling factors such as development and growth are referred to as genes (Carter, Moschini & Sheldon 3). Within each body cell, genes would be...

...bacterium contains cytoplasm enclosed by a membrane and a cell wall. The bacterial cell contains some genetic material with the purpose of carrying the body’s instructions to the cell. Bacteria differ in their nature as some contains additional features such as flagella, which helps them in moving and protecting the slim capsules. They also exist in varying shapes and sizes because some are rod shaped, round, comma-shaped and spiral. Some bacteria cause diseases while many others are important to human beings as they support them in living healthily (Storey 339...
