What are genes? A gene is a piece of DNA that codes for RNA molecules. What is genetic engineering? Genetic engineering is the process where humans alternate the genome of organisms using biotechnological processes. It allows scientists to transfer genes from one organism to the next. FIGURE 1.1: A scientist manipulating an organisms DNA Genetics have been an impact on agriculture for thousands of years by the means of artificial selection. Farmers control the way their plants reproduce so that each new generation has many parents’ genes as possible. This is another form selective breeding which genetic engineering. There has been an increase in crop yields in cereal crops. They have become resistant to disease. The nutrition value of the crops has been enhanced. Plant breeding methods can be slow and unpredictable. An exact characteristic is created in one generation very accurately by genetic engineering. Only closely related plants can be combined during plant breeding. Genetic engineering has allowed new characteristics in important crops to improve their strong resistance to pests, their nutrition value, taste and quality (especially tomatoes), resistance to extreme weather conditions. The use of GM crops has expanded into 40 countries. FIGURE 1.2: The distribution of genetically modified foods around the world Many plant and animal species that are domesticated have been distributed around the world from the place where they’ve been domesticated.
