Title Gene expression with E.coli bacteria through means of transformation with plasmid DNA Abstract Science has discovered that with gene expression and genetic engineering‚ DNA and organisms can be manipulated like never before. This has become an extraordinary discovery because it has lead us to countless medicinal products and cures for diseases and continues to serve as a great asset as research continues. This lab consisted of introducing a plasmid

An Introduction to Probiotics Probiotics are live microorganisms (in most cases‚ bacteria) that are similar to beneficial microorganisms found in the human gut. They are also called “friendly bacteria” or “good bacteria.” Probiotics are available to consumers mainly in the form of dietary supplements and foods. They can be used as complementary and alternative medicine (CAM).1 To find out more about topics and resources mentioned in this fact sheet‚ see “For More Information.” Key Points

Cody Trezise 06 october 2011 Chain of infection & how bacteria grow. Reference: http://faculty.ccc.edu/tr-infectioncontrol/chain.htm In this essay I am going to be describing and explaining n about how pathogenic organisms grow and spread‚ by explaining each stage of the chain of infection‚ step by step and what they involve. This representive is used to help us understand the infection progression. A circle of linked components represent what happens in the cycle of infection

differences in ribosomal RNA structure. Ribosomal RNA is a molecular building block for ribosomes . Under this system‚ organisms are classified into three domains and six kingdoms . The domains are Archaea‚ Bacteria‚ and Eukarya. The kingdoms are Archaebacteria (ancient bacteria)‚ Eubacteria (true bacteria)‚ Protista‚ Fungi‚ Plantae‚ and Animalia. The system used for classifying organisms change due to new discoveries being constantly made making some organisms harder to classify into a specific kingdom

resistance can be genetically transformed into plants. In bioremediation‚ bacteria can be genetically transformed with genes enabling them to digest oil spills. In medicine‚ diseases caused by defective genes are beginning to be treated by gene therapy; that is‚ by genetically transforming a sick person’s cells with healthy copies of the defective gene that causes the disease. You will use a procedure to transform bacteria with a gene that codes for Green Fluorescent Protein (GFP). The real-life

The Endosymbiont Hypothesis and the evolution of the Chloroplast and Mitochondria Dr Lynn Margulis is seen as the first person to have put forward the Endosymbiont Hypothesis which is based on a theory which explains the likely origin of the mitochondria and chloroplast (plants) in eukaryote organisms which we observe today. Dr Margulis received evidence from all over the world and from many scientific researchers and experiments‚ Margulis simply had to put all the evidence together to form her
