Genetic Engineering
Genetic Engineering
• Definition
• Changing the genetic makeup of cells by
introducing or eliminating specific genes
using molecular biology techniques.
• Also known as biotechnology
Why would we do it?
• Can change properties in a positive way
–
–
–
–
–
Grow higher
Grow faster
Pest resistant
More nutritious
Sweeter taste
So What’s the Catch?
• Positive changes can have negative
effects too
– Some may be tolerable
– Some may be devastating
Gene Corn Project
• Goal
– Design a genetically engineered corn product
– Develop marketing campaign
• Genetic Engineering Design Company

Marketing Campaign
• The following is required
– PowerPoint presentation, or a poster display large
enough to be read by the class, or a flyer to distribute
to the class.
– Product name that reflects the modifications.
– Must describe the genes you modified and why you
modified them.
– Must identify the advantages of your modifications.
– Must describe why people should buy your product.
– Must give a 2-minute presentation, each group
member speaking for 1 minute.
Engineering Design Process
•
•
•
•
•
Identify product need
Research available options
Identify pros and cons of design options
Choose best design
Communicate design choice to broader
audience
• Critically evaluate other engineering
designs to identify the appropriate
solution
