(Opening of your presentation) Biotechnology: How much do you know? 1. Biotechnology is: a. Using nuclear power to make life from nonliving things such as rock and soil b. using microorganisms, plant cells or other living matter to make things c. a rare species of owl d. a technique that uses lightning bolts to create new life 2. Genetic engineering is: a. Changing living things by changing their genes b. the deliberate transfer of genes between and among species by humans c. changing stones into living things d. dependent on finding and moving DNA What is Biotechnology? Biotechnology is using biological processes to make products. The word biotechnology can be broken into two parts. Bio is for biology, while technology refers to the tools and processes used for making things. Biotechnology has been used for centuries to make things such as bread by using yeast. Why is Biotechnology important? From crop improvements to new medications, biotechnology has improved our lives and opened up a whole new world of career opportunities. In the beginning: Gregor Mendel, a 19th century monk, set the stage when he used pea plants to figure out how parents pass traits on to their offspring. When James Watson and Francis Crick proposed a structure of DNA that explained how it is able to transmit information from one generation to the next, modern-day biotechnology emerged. Scientists have utilized biotechniques to splice important genes, stretches of DNA that carry the information that makes the organism what it is, into developing crops and animals to create products for human use. Biotechnology and Agriculture Biotechnology helps farmers produce food in ways that may be better for the environment. Scientists today are developing plants that are resistant to specific herbicides and insects. This often means fewer chemicals need to be used to protect crops from weeds and pests that rob the crops of their vigor and yield. Biotechnology has the potential to create better food for everyone. A new biotechnology has emerged over the past few decades. This new biotechnology, genetic engineering, uses molecular tools to move genes from one organism to another, changing one or more traits of the recipient organism. For example, tomato plants are being developed using a scorpion gene. Researchers hope that built-in scorpion venom will guard off pesky deer that graze on fields. FACT: During 1999 in the United States, about 37 percent of planted corn, 47 percent of soybeans and 48 percent of cotton were genetically modified. There were approximately 100 million acres of biotech crops worldwide. (Continue with your lesson plan)
