1. Explore - Understanding GMOs and Their Impact
In this section, students develop a foundational understanding of genetically modified organisms (GMOs), how they are created, and why their impact can be complex. The Explore phase introduces key biological and biotechnological concepts needed to understand genetic modification before engaging in modelling, AR-based analysis, and creative activities later in the unit.
1.3 Examples of GMOs in Real Life
GMOs are widely present in modern biotechnology and agriculture. Common examples include:
- Genetically modified crops, such as maize or soybeans, designed to resist pests or tolerate environmental stress. Bt maize or Roundup Ready soybeans, designed to resist pests or tolerate herbicides (MON810, approved 1990s). (https://en.wikipedia.org/wiki/Genetically_modified_maize)
- GMO microorganisms, used to produce medicines like insulin or vaccines. Example: E. coli engineered to produce human insulin (Humulin, FDA-approved 1982)
- Research organisms, modified to study gene function and disease mechanisms.
These examples show that GMOs are not limited to food production but play a broader role in science and medicine.
