Genetic modification (GM) Changing the genes of a living thing, often by adding genes from another living thing. Gene Jury TRUE or FALSE TRUE! Did scientists add a spider gene to TRUE! It is amazingly strong and light, goats to make web silk in goat’s milk? it is called BioSteel. TRUE! TRUE or FALSE TRUE! The Enviropig in Canada/US Did scientists add genesisfrom mice and now, its waste is much polluting bacteria to pigs, so theless pigs poo wasto the environment. The meat from the less polluting? Enviropig may be in their shops soon. TRUE or FALSE FALSE Did scientists a gene to make these FALSE! add An artist called Camille tiny Allen made thebabies? babies out of clay. TRUE TRUE! or FALSE GM hens produce human interferon anti-viral and anti-cancer drug. create a GM hen BUTDid the scientists company that funded the research thatbust laysineggs help fight cancer? went 2007.that Making GM animals is very costly and time-consuming! Do you know of any medicines produced by GM creatures ?

Do we really need it? Modified genes can escape, into wild plants and animals It is interfering with nature. Pollen from some GM plants can harm insects like bees GM seeds and animals and genes are patented (Copyright) In the UK GM is used extensively in labs and in food processing. It is possible that the UK government want to try GM crops in the future. What do you think? When is GM ok?
