UNRAVELING THE DNA MYTH The spurious foundation of genetic engineering
نویسندگان
چکیده
Biology once was regarded as a languid, largely descriptive discipline, a passive science that was content, for much of its history, merely to observe the natural world rather than change it. No longer. Today biology, armed with the power of genetics, has replaced physics as the activist Science of the Century, and it stands poised to assume godlike powers of creation, calling forth artificial forms of life rather than undiscovered elements and subatomic particles. The initial steps toward this new Genesis have been widely touted in the press. It wasn’t so long ago that Scottish scientists stunned the world with Dolly, the fatherless sheep cloned directly from her mother’s cells; these techniques have now been applied, unsuccessfully, to human cells. ANDi, a photogenic rhesus monkey, recently was born carrying the gene of a luminescent jellyfish. Pigs now carry a gene for bovine growth hormone and show significant improvement in weight gain, feed efficiency, and reduced fat. Most soybean plants grown in the United States have been genetically engineered to survive the application of powerful herbicides. Corn plants now contain a bacterial gene that produces an insecticidal protein rendering them poisonous to earworms.

متن کاملUnraveling the Effects of Process Control Agents on Mechanical Alloying of Nanostructured Cu-Fe Alloy
Nanostructured Cu-20Fe alloy was synthesized by mechanical alloying process and the effects of process control agents (PCA) on the phase formation, crystallite refinement and morphology of powder particles were studied. The dissolution of Fe into Cu matrix and the morphology of powder particles were analyzed by X-ray diffraction (XRD) technique and scanning electron microscopy (SEM), respective...
متن کاملDHPLC Applications: Finding DNA Variation on the Y Chromosome
Denaturing High-Performance Liquid Chromatography (DHPLC) is a recently developed technique forthe detection of single nucleotide polymorphisms (SNPs) and mutations. It involves the comparisonbetween two or more DNAs as a mixture of denatured and reannealed PCR products. The methodologyis based on the principle of reversed phase liquid chromatography and uses a unique DNA sepa...

Background: Sugarcane is a monocotyledonous crop that is cultivated in the tropical and subtropical regions of the world. One of the most important criteria, influencing the efficiency of the sugarcane transformation is known to be related to physical and biological factors during the transformation procedure. Objectives: The objective of this research was to study the response of callus induc...
متن کاملSimple Sequence Repeats Amplification: a Tool to Survey the Genetic Background of Olive Oils
A reliable DNA extraction method for use on extra virgin olive oil based on a commercial kit was defined, and the possibility of using this DNA for fingerprinting the original cultivar was demonstrated. The genetic traceability of single-cultivar virgin olive oil from two cultivars (Carolea and Frantoio) was achieved by identifying the varieties from which they were produced. This involved the ...
