Each word may be used once, more than once, or not at all. adding bacteria crops family insects minerals organism removing viruses vitamin weeds In genetic engineering the genetic material of an is changed by , changing or inserting individual genes. An example of this is inserting a human gene into so that they produce human insulin. Crop plants have genes inserted into them to make them resistant to herbicides. Herbicides kill . Crop plants can also be genetically engineered by inserting a gene so that they produce a which is a nutrient needed by humans in very small amounts.

The diagram shows five stages in genetic engineering. stage 1 The DNA making up a human gene is isolated using restriction enzymes. stage 2 The DNA of a bacterial plasmid is cut open using restriction enzymes. stage 3 The DNA of the human gene is inserted into the bacterial plasmid DNA. stage 4 The plasmid containing the human gene is put back into a bacterium. stage 5 The bacteria with the human gene divide and make the human protein. Which stages involve the formation of sticky ends?
