Prelim Predictor '18: Science and Technology SIVA PRASAD
About Me . Bachelors and Masters in Physics from Indian Institute of Science (ISc), Bangalore .INSPIRE Scholar, DST Govt. of India Interested in Physics, current affairs, economics.... . Physicist, Blogger, Teacher.... Wrote UPSC CSE Mains 2017 Research Publication in Journal of Applied Physics
Objectives of the course . Myth Breaker - Science is tough (LOL) . To make science easy, interesting and understandable . Attempt all science related prelims questions with an accuracy of above 85% Less time and effort but more marks in Prelims . You can forget facts but you wl never forget concepts!
GM Mustard . In news: Genetic Engineering Appraisal committee gave a nod for GM Mustard for commercial use . GMO A GMO (genetically modified organism) is the result of a laboratory process where genes from the DNA of one species are extracted and artificially forced into the genes of an unrelated plant or animal. . Genetic modification done with the objective of producing superior crops ex. High nutritional value, drought resistance, short maturity period, higher yield etc.
Pros of GM Mustard . Better yield and pest resistance . Indian imports huge amount of GM oil anyway . Indigenous - Developed by DU based center for genetic manipulation of crop plants
Cons of GM Mustard Environmental risks involved . Health impact . Impact on food chain - Biomagnification? Lack of transparency - the data based on which GEAC approved is not available on public domain
GEAC . Genetic Engineering Appraisal committee . Statutory body under Ministry of Environment, Forests and Climate Change . Apex body for approval for proposals relating to release of genetically engineered organisms and products into the environment The Trials for approval are only considered by GEAC after the Review committee on genetic manipulation under Department of Biotechnology approves
Concerns . GEAC is an opaque body . Members and how they are chosen is unknown . Basis of decisions made by GEAC is unknown Data is not made available in public domain Agriculture is a state subject
Canola It is an international trade name for mustard carrying lower levels of eruct acid; cosidered healthy . In news Canola villages . Canola villages: villages would not only produce canola but also have oil extraction units in the village so that canola oil can be extracted
Cartagena Protocol on Biosafety to the Convention on Biological Diversity It is an international agreement on biosafety as a supplement to the Convention on Biological Diversity effective since 2003. . The Biosafety Protocol seeks to protect biological diversity from the potential risks posed by genetically modified organisms resulting from modern biotechnology. The Biosafety Protocol makes clear that products from new technologies must be based on the precautionary principle and allow developing nations to balance public health against economic benefits. . It will for example let countries ban imports of genetically modified organisms if they feel there is not enough scientific evidence that the product is safe and requires exporters to label shipments containing genetically altered commodities such as corn or cotton.
