Identification of Chemotaxis Protein Substrates in Thiomicrospira crunogena Introduction Thiomicrospira crunogena is a Gram negative, aquatic, colorless sulfur oxidizing, chemolithoautotrophic bacterium. Cells are spiral shaped 0.2-0.3 µm in diameter and 1-2µm long, some individual cells can reach up to 30 µm long (3). T. crunogena is motile via a singular polar flagellum. It is the first deep-sea autotrophic hydrothermal vent bacterium to have its genome fully sequenced and annotated

strategies for testing are also discussed. THE BASICS Isolation of DNA and Polymerase Chain Reaction (PCR) DNA or RNA for genetic testing is almost always isolated from peripheral-blood leukocytes. This requires that the blood be drawn in tubes containing some sort of anticoagulant. The preferred anticoagulants are either citrate or EDTA. The cells are lysed followed by removal of the other cellular components and precipitation of the DNA or RNA in ethanol. One of the drawbacks of this approach is that

genetic makeup of that organism. It can also be referred to as transgenic, due to the process being the transfer of genes from one organism to another. Other names also referred to are biotechnology, gene splicing, genetic engineering, or recombinant DNA technology, all of which meant the same thing. Transferring genes from one organism to another, to enhance or improve that organism. Genetically modified organisms can be foods, plants and animals. Genetic Modification is done in a laboratory by extracting

able to be controlled better by having a synthetically produced insulin through the recombinant plasmid inserted into a bacteria- Escherichia coli. Insulin that is able to be produced in a large amount and a much lower cost to be compared to the extraction from cattle or pigs which is the previous method in getting insulin. Moreover, Dr. Michio Kaku which is a physicist and also a futurist have shown us in his video about the scientists are now trying to repair and grow human organs and tissues

Running head: The Ethics of Cloning The Ethics of Cloning Team D: Casey Krueger, Erin Lee, Ferdinand Malarayap, Marvin Monge, and Ibrahim Mortada August 14, 2011 DeVry University Online Stem cell research and cloning have become a major topic of interest in countries all around the world ever since Dolly the sheep was successfully cloned in 1997. Every single country has their own views about stem cell research and cloning because of their moral and ethical issues. Muslims, for example

unable to visualize the mutation at a chromosomal level, as both wild-type and eyeless flies looked similar. The experiment involved electrophoresis and Polymerase Chain Reaction (PCR) through which we were able to isolate and amplify the needed DNA eyeless DNA. The difference between the wild-type Drosophila melanogaster and the eyeless Drosophila melanogaster is approximately only 500-nucleotide base pairs. As we see the eyeless phenotype is approximately 3000 base pairs in length while the wild-type
