Questions and Answers
Where does the inserted gene sequence in a transgenic crop come from?
It may come from another unrelated plant or a completely different species.
What is an example of a transgenic crop and its unique trait?
Transgenic Bt corn, which produces its own insecticide from a gene of a bacterium.
What is a transgenic crop plant?
A plant that contains a gene or genes artificially inserted instead of acquiring them through pollination.

Study Notes
Transgenic Crop Plants
- A transgenic crop plant contains a gene or genes that have been artificially inserted, rather than acquired through pollination.
- The inserted gene sequence is known as the transgene.
- The transgene can come from another unrelated plant or from a completely different species.
- Example: Transgenic Bt corn, which produces its own insecticide, contains a gene from a bacterium.
Genetically Modified (GM) Crops
- Plants containing transgenes are often called genetically modified (GM) crops.
- All crops have been genetically modified from their original wild state over time through domestication, selection, and controlled breeding.
