| | Genetic Code Lecture | | 2008-07-22 19:59:00 | | The genetic code is the set of rules by which information encoded in genetic material (DNA or RNA sequences) is translated into proteins (amino acid sequences) by living cells. Specifically, the code defines a mapping between tri-nucleotide sequences called codons, and amino acids; every triplet of nucleotides in a nucleic acid sequence specifies a single amino acid. Because the vast majority of genes are encoded with exactly the same code (see #RNA codon table), this particular code is often referred to as the canonical or standard genetic code, or simply the genetic code, though in fact there are many variant codes; thus, the canonical genetic code is not universal. For example, in humans, protein synthesis in mitochondria relies on a genetic code that varies from the canonical code.It is important to know that not all genetic information is stored as the genetic code. All organisms' DNA contain regulatory sequences, intergenic segments, chromosomal structural areas, which can contri... | | By: Biosolution | | |
| | Genetic Testing: Fact or Friction? | | 2008-07-10 08:09:00 | | Companies which offer genetic-testing services directly to consumers via the Internet have raised debate over how medical data inherent in an individual's genetic profile should be used and regulated. This new form of medical information falls short of being a diagnostic aid, and California state la... | | By: CR4: The Engineer's Place for Discussion & New | | |

| Genetic study finds malarial traits in Northeast | | 2008-07-03 04:18:00 | | Shillong, July 3 (PTI) A study by the Anthropological Survey of India (ASI) on the genetic characteristics of the inhabitants of India's Northeast considered as a 'malaria zone' - may open up a fresh lead among researchers to develop a new drug for the mosquito-related disease.The ongoing study has found that deficiency of enzyme G-6-PD (glucose-6-phosphate dehydrogenase), which helps red blood cells (RBCs) function normally is a common sex-linked trait in the region, M Arabind Singh of the ASI's Northeast Regional Centre told PTI on the sidelines of an exhibition here.G-6-PD is one of many enzymes that help the body process carbohydrates and turn them into energy. It also protects red blood cells from potentially harmful byproducts that can accumulate when a person takes certain medications or when the body is fighting an infection.The ASI study detected cases of disorder like jaundice among those G-6-PD-deficient persons who had intake of chloroquine.

| | Genetic Engineering | | 2008-07-02 16:16:00 | | Genetic engineering, recombinant DNA technology, genetic modification/manipulation (GM) and gene splicing are terms that apply to the direct manipulation of an organism's genes.Engineering is different from traditional breeding, where the organism's genes are manipulated indirectly; genetic engineering uses the techniques of molecular cloning and transformation to alter the structure and characteristics of genes directly. Genetic engineering endeavors have found some success in improving crop technology, the manufacture of synthetic human insulin through the use of modified bacteria, the manufacture of erythropoietin in Chinese hamster ovary cells, and the production of new types of experimental mice such as the oncomouse (cancer mouse) for research.Since a protein sequence is specified by a segment of DNA called a gene, novel versions of that protein can be produced by changing the DNA sequence of the gene.EngineeringThere are several ways through which genetic engineering is accompli... | | By: Biosolution | | |
| | A Microsatellite-guided Insight Into The Genetic Status Of The Adi Tribe | | 2008-07-02 02:42:00 | | ScienceDaily (July 1, 2008) — North-east India has always been a hotspot for population geneticists due to its unique, strategic geographic location and the presence of linguistically, culturally and demographically diverse populations practicing varied occupations (from hunter-gathering to settled agriculture).There are an estimated 532 tribal communities who inhabit the different geographical regions, who vary in their morphological features and ethnic origins (Australian, African, East Asian) of varied cultural features and who belong to three linguistic families (Austro-Asiatic, Dravidian and Tibeto-Burman). These are important in understanding the genetic history and peopling of the Indian subcontinent, and to derive further insights into the antiquity and past human migrations to other parts of Asia and their genetic relatedness.In a new study, Dr T.S. Vasulu and colleagues at the Indian Statistical Institute examine, for the first time, the genetic status of sub-tribes of one ... | | By: Tingplik Express | | |

| Microarray Method for Genetic Testing | | 2008-06-10 21:46:00 | | Genetic testing allows the genetic diagnosis of vulnerabilities to inherited diseases, and can also be used to determine a person's ancestry. Normally, every person carries two copies of every gene, one inherited from their mother, one inherited from their father. The human genome is believed to contain around 20,000 - 25,000 genes. In addition to studying chromosomes to the level of individual genes, genetic testing in a broader sense includes biochemical tests for the possible presence of genetic diseases, or mutant forms of genes associated with increased risk of developing genetic disorders. Genetic testing identifies changes in chromosomes, genes, or proteins. Most of the time, testing is used to find changes that are associated with inherited disorders. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person's chance developing or passing on a genetic disorder. Several hundred genetic tests are currently in use, and more are ... | | By: Biosolution | | |
| | A Genetic Clue to Quitting Smoking | | 2008-06-03 18:44:38 | | By Alice ParkNew genetic research helps explain why some smokers respond better to certain smoking-cessation programs than others, according to scientists at Duke University and the National Institute on Drug Abuse.Reporting this week in the Archives of General Psychiatry, scientists describe for the first time a set of genes, about 100 in all, that seem to predict how well a smoker will respond to two different types of quitting programs — nicotine replacement or bupropion (Zyban). Nicotine-replacement methods, including the patch, pill and gum, work by weaning the smoker off nicotine gradually, usually over a period of weeks or months. Bupropion, on the other hand, is an antidepressant, which does not contain nicotine; instead, it works to curb nicotine cravings by interfering with the reward circuit in the brain, where addictions — to nicotine and other drugs, or behaviors — are reinforced. Nationally, about 70% to 80% of smokers say they want to quit, but any single attempt, ... | | By: angelite nurses | | |

| | New Genetic Marker for Crohn's Disease - Living with Crohn's Disease Research | | 2008-04-05 20:45:00 | | FRIDAY, April 4 (HealthDay News) -- Researchers have identified new genetic markers for Crohn's disease and ulcerative colitis in a study they say provides further evidence that people of Ashkenazi Jewish descent are more likely to develop the conditions.Up to 30 percent of people in the United States with inflammatory bowel disease (IBD) have a family history of the condition, and about 25 percent of those families have histories of both Crohn's and ulcerative colitis, according to background information in this multi-center American and Canadian study. People of Ashkenazi Jewish (eastern European) descent are at least twice as likely to develop a form of IBD and are more likely to have a family history of IBD.Crohn's is most frequently characterized by inflammation of the final section of the small bowel and parts of the colon, while ulcerative colitis involves inflammation of the internal lining of the rectum and colon.In this study, researchers looked for DNA variations called sing... | | By: Living with Crohn's Disease | | |
| | Genetic Complications of the Amish World | | 2008-04-01 15:20:34 | | http://amishwiki.org/tiki-read_article.php?articleId=31 The Amish
The Old Order Amish are a religious community that eschews many aspects of modern life and who minimizes contact with the outside or “English” world. Also called the “plain people” due to their austere dress, most are living the same lifestyle as many of their ancestors.
Genetic Restriction
This is largely a closed community with few converts from the outside and essentially no intermarriage with those who are not also Amish. This means a very restricted gene pool and an increased risk of genetic illnesses. It also means difficulty in caring for the most severely afflicted due to lack of accessibility to modern medical equipment.
Inbreeding in Lancaster Co., PA
Lancaster County in Pennsylvania is a good example of the extent of the problem. Approximately 200 Swiss citizens immigrated to this area and have intermarried and interbred for what is now more than a dozen generations. This closed gene pool means ... | | By: Amish Furniture Reviews | | |
