The Life of Escherichia Coli Escherichia Coli 0157:H7 bacterium can live in the intestines of cattle‚ therefore meat can become infected during slaughtering. You can contract this bacterium by eating undercooked meat‚ especially ground beef. Escherichia Coli 0157:H7 can also be contracted by eating contaminated fruits or vegetables‚ as well by drinking raw fruit juices or milk‚ or sewage contaminated water. Infection can also be spread via person to person. Escherichia Coli 0157:H7 can also

Current status on: Biopharming: crops for the production of Therapeutic & Pharmaceutical proteins Biopharming‚ also known as molecular farming‚ is the production of pharmacologically active substances‚ either induced or increased through the application of genetic engineering. The first instance of artificial gene expression in an organism to produce a pharmaceutical product was the synthesis of insulin in the bacterium E. coli (Goeddel et al.‚ 1979). This type of biotechnology has since moved

Targeted expression of another gene (X) can be induced by genetic crossing. (Haseloff) Fig1. Shows the two T-DNA constructs. Agrobacterium-mediated transformation Agrobacterium-mediated transformation is used to transform plant cells with a plasmid containing the modified GAL4-VP16 and UAS-GFP genes. The modified GAL4-VP16 gene is positioned adjacent to the Tr border sequence

Cloning is a process in which an exact replica is made from an organism‚ cell‚ or tissue. The duplicate contains the same genetic information as the original. When most people think of cloning they think of the cloning of humans that is seen in movies. Cloning can occur in many ways than just one. A lot of cloning happens naturally. Bacteria are an example of naturally occurring cloning. Bacteria can produce a genetically identical offspring through a process called asexual reproduction. In asexual

burgdorferi as compared with other bacteria is its unusual genome‚ which includes a linear chromosome and numerous linear and circular plasmids. Long-term culture of B. burgdorferi results in a loss of some plasmids and changes in expressed proteins. The loss of plasmids results in the organism’s loss of ability to infect laboratory animals‚ suggesting that the plasmids encode key genes involved in virulence. Cultivation Unlike Treponema pallidum‚ Borrelia burgdorferi can be cultivated in vitro
