WHAT DOES IT MEAN BIOTECHNOLOGY? The word «Biotechnology» means the use of living organisms or their parts to produce useful substances to men Traditional Innovative

Traditional biotechnologies are used for thousands of years, such as are born thousands of years ago… Traditional biotechnologies are used for thousands of years, such as Agricolture Farm Fermentative activity of the microorganisms

What is an OGM? “An organism or microorganism whose genetic material has been altered by means of genetic engineering.” How to create a transgenic organism? Gene addition Gene subtraction Cell fusion

Biolistic method (Gene Gun) PDS1000 Microparticle Delivery System Helium chamber Rupture disk Macrocarrier DNA coated gold particle Stopping screen Focusing device PDS1000 Microparticle Delivery System Target tissue

Action fields of OGM: Nutritive contents Organoleptic charapteristics Pesticides Fruit and vegetables out of season Economy

Bad points about OGM Allergic problems Resistant bacteria and insects Reduction of biodiversity Argentina, OGM soya Industrial monopoly BUT Hawaii, transgenic papaya India, Bt cotton

Thank you, I hope you enjoyed it It must be remembered the meaning of "cultivating" which is not just to grow plants, but also to take care, respect, serve. Thank you, I hope you enjoyed it
