Can we give an organism a unique trait like pesticide resistance, have it make a novel protein like insulin, or get it do something for us like clean up radioactive waste. Genetic Engineering • Some organism has a good trait. EX: it glows in the dark. • You want to make another organism glow in the dark. • Take the gene for glowing in the dark out of the first organism and put it in the other one. • Now they both glow in the dark. • How does this work? Genetic Engineering • Making insulin. TTGCT TCTGCTAACATCGATCT TCAGCTAC AACGA AGACGATTGTAGCTAGA AGTCGATG Recombinant DNA Bacteria makes insulin. Transgenic Organisms • Genetically modified organisms or organisms with changed genes, will produce babies with their new traits. • They are now transgenic or have genes from several organisms. • How can this be helpful to humans? • Tomatoes and Fish? Golden Rice? Cloning • Make an exact copy of an organism. • Take the nucleus out of a donor egg cell. • Put the nucleus of the donor cell into an empty egg. • Shock it. • The new fused cell begins dividing. • Put the new cell into a foster mother. • The baby is born. • It is the exact copy of the animal where the nucleus came from. Clone this sheep. Why not clone tasty beef cattle? Cloning People • Would you want a clone of yourself? • You could harvest its organs for transplant into yourself. • You could just clone yourself to harvest the stem cells of the embryo, then use them to fix yourself. Bill Nye GMO Video Quiz • What two ways do we make new plant species with different traits? Which process is faster? • What are some benefits of Genetically Modified Organisms? • What are some fears of Genetically Modified Organisms?
