How Does One Get Lymphoma? | Health Tips
For one, despite the thousands of hours spent on medical research and laboratory testing the actual cause of the disease is still an unknown. DNA mutation is one of the plausible cause of why lymphoma develops but what happens why DNA have to mutate remains a big question to the medical science community. Medical scientists, nevertheless, have found several factors that trust possibly increase the risks of developing lymphoma. As you capability have already guessed, the two prevailing factors are genetic and environmental factors. Genetics for one is still a complicated issue that famously [more...]

Evaluation of Five Methods for Total DNA Extraction from Western ...
DNA extraction is a routine step in many insect molecular studies. A variety of methods have been used to isolate DNA molecules from insects, and many commercial kits are available. Extraction methods need to be evaluated for their efficiency, cost, and side effects such as DNA degradation during extraction. Methodology/Principal Findings From individual western corn rootworm beetles, Diabrotica virgifera virgifera, DNA extractions by the SDS method, CTAB method, DNAzol® reagent, Puregene® solutions and DNeasy® column were compared in terms of DNA quantity and quality, cost of materials, [more...]

The researchers at Johns Hopkins took six sets of cancerous and normal tissue from four bowel and two breast cancer patients and “sequenced” – or decoded – the complete set of DNA for each patient. By comparing DNA from healthy and cancerous tissue, the researchers could spot where large parts of genetic code had been altered. These changes occur only in cancer cells, making them ideal biomarkers for the disease. Once the researchers found areas where DNA had been rearranged, they looked for the same changes in DNA shed from tumours into the patients” blood. Using blood samples [more...]

How DNA is Used in Paternity Testing?
Recently, companies have begun selling DNA paternity tests over the counter at drug stores, which facilitates home testing. However, results are usually inadmissible in court due to the chance of surreptitious DNA collection or false identification of the tested individuals. The legality of testing another person’s DNA without their consent varies by state. If a paternity test is to be used in a court of law, chain of custody of the DNA sample must be verified. This means that every step of the paternity testing process and analysis is documented, from the collection of the DNA sample by an [more...]

20000 Genes Under the Brain: Genes->Brain->Man
To assess gene expression in each small bit of tissue, researchers expose its RNA to a gene chip, or DNA microarray. These small devices are coated with clusters of identical DNA molecules, called probes, within separate areas. Each probe binds to the RNA of a specific gene—the one that contains a complementary set of chemical units, or bases. In a DNA molecule, the base adenine (A) sticks to thymine (T), and guanine (G) pairs with cytosine (C). Thus, the sequence that would bind to the strand illustrated above is (from top to bottom): T, C, C, T, G, C, A. In this way, a chip records which [more...]

X-rays and toxic chemicals affect DNA in so-called somatic cells, or adult tissue, rather than the germline cells that go on to form eggs and sperm.
