Questions & Step-by-Step Solutions
Which of the following is a genetically modified organism (GMO)? (2019)
Step 1: Understand what a genetically modified organism (GMO) is. A GMO is an organism whose DNA has been altered using genetic engineering techniques.
Step 2: Identify examples of GMOs. Common examples include certain crops like Bt cotton, which have been modified for specific traits.
Step 3: Learn about Bt cotton. Bt cotton is a type of cotton that has been genetically modified to produce a toxin from a bacterium called Bacillus thuringiensis (Bt).
Step 4: Understand the purpose of Bt cotton. The modification helps the cotton plant resist pests, reducing the need for chemical pesticides.
Step 5: Conclude that since Bt cotton has been genetically modified to express a bacterial toxin for pest resistance, it is indeed a GMO.
