The benefits and hazards of gene technology

BenefitsThrough element engineering science, it is now possible to produce:? genetically circumscribed organisms for a specific purpose. Previously, much(prenominal) genetic change would give fashion to be brought about by selective breeding which requires organisms to be of the same species (able to breed successfully together), takes many generations and involves transfer of square(p) genomes, complete with undesirable background genes. Gene technology is much faster and involves transferring one or few genes, which may numerate from completely un associate to organisms, even from different kingdoms. ? specific products, such(prenominal) as human insulin and human growth hormone, thereby decrease the dependency on products from other, less reliable sources, such as copper or cow insulin. ? reduce use of agrochemicals such as herbicides and pesticides since crops sack up be made resistant to concomitant herbicides, or can be made to contain toxins that killinsec ts. ? slap-up up specific pollutants and waste materials ? bioremediation? potential for use of gene technology to treat genetic diseases such as cystic fibrosis (see below) and severe combined immunodeficiency disease (Severe Combined Immune Deficiency) as well as in cancer treatment. HazardsGenes inserted into bacterium could be transferred into other bacterial species, potentially including antibiotic drug resistance genes and those for other materials, whichcould result in antibiotic resistance in pathogens, or in bacteria that can produce toxic materials or break down flight useful materials.

Regulation is designed to minimise ther isks of escape of such genes. There is littl! e evidence that such genes haveescaped into wild bacterial populations. Crop plants have, by their nature, to be released into the environment to grow, and many millions of hectares of genetically engineered crops, both experimental and commercial, are planted across the globe. So far, fears that they might turn out to be ?super-weeds?, resistant to herbicides and ranch uncontrollably, or that their genes might transfer into other closely related wild species, forming...
