What Are Transgenic Organisms?

A genetically modified organism (GMO), also known as a transgenic organism, is any organism whose genetic material has been altered using genetic engineering techniques

How Are Transgenic Organisms Made?

Genes of one species can be modified, or genes can be transplanted from one species to another

Recombinant DNA technology is used

Other Examples of Transgenics

Spider silk-manufacturing goats! For eventual commercial production of spider silk.

Less flatulent cows to reduce methane emissions!

Discussion Questions

Should the creation of transgenic organisms be allowed?

Why or Why Not?

Should there be limits on experimenting? Creating? Intellectual liabilities?

Other questions?
