GE Genetic Basics

DNA is the root of all inheritance and the key to understanding the basics of all biological inheritance and genetics.

Uses for Genetic Engineering

The possibilities of this genetic engineering are endless, and everyone from medicine to industry is scrambling to adopt it and adapt it to their specific needs.

Genetic Engineering Methods

Genetic engineering changes or manipulates genes in order to achieve specific results, and there are many ways to "engineer" genetic material including fixing defective genes, replacing missing genes, copying or cloning genes, or combining genes.

Labeling Genetically Engineered Food

How is genetic engineering used in food production? What political, environmental, and production obstacles could arise in the effort to label genetically engineered foods? What food traits would you like to see genetically engineered?

Pre-viewing Questions
  • Should genetically engineered foods be labeled? Why or why not?
Post-viewing Questions
  • How is genetic engineering used in food production?
  • What political, environmental and production obstacles could arise in the effort to label genetically engineered foods? What could be done to overcome these problems? Is it worth the effort?
  • What food traits would you like to see genetically engineered?

 

Genetic Engineering: Feeding the World

Genetic Engineering and the Animal Kingdom

How can GE be used with animals? What are the benefits and risks of using genetic engineering with livestock or with endangered or extinct animals?

Pre-viewing Questions
  • Think of someone who could have benefited from genetic engineering in the treatment of disease. How would this have changed the present? Is this an ethical use of science?
Post-viewing Questions

Genetic Engineering: Human Cloning

How does cloning work? What situations might be viewed as ethical uses of human cloning? Unethical?

Pre-viewing Questions
  • Think of someone who could have benefited from genetic engineering in the treatment of disease. How would this have changed the present? Is this an ethical use of science?
Post-viewing Questions
  • How does cloning work?
  • What situations might be viewed as ethical uses of cloning? Unethical? Are you doubtful, fearful, or hopeful about human cloning?

 

Moral/Ethical Dilemmas of Genetic Engineering

What are the potential consequences, positive and negative, of discovery in the genetic engineering field? Who should be involved in determining the ethical limitations of the uses of genetic engineering?

Pre-viewing Questions
  • Who should be involved in determining the ethical uses of genetic engineering?
Post-viewing Questions
  • What are the potential consequences, positive and negative, of discovery in the genetic engineering field?
  • How could the public be informed of the issues of genetic engineering in a non-biased way?
  • What ethical and moral issues should be debated when discussing the effects of genetic engineering?

 


Produced from 2001 through 2004, Iowa Public Television's Explore More online and broadcast series engages students in problems they can relate to, provides compelling content for investigation and gives students opportunities to form their own points of view on contemporary issues.
