10 Questions
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.
What is the common term used to refer to plants containing transgenes?
Genetically modified (GM) crops.
How have all crops been genetically modified over time?
Through domestication, selection, and controlled breeding over long periods.
What distinguishes a transgenic crop plant from a non-transgenic crop plant?
It contains genes acquired through artificial insertion.
Why are plants containing transgenes often referred to as genetically modified (GM) crops?
They have genes from unrelated organisms inserted into them.
How is a transgenic crop different from a non-transgenic crop in terms of gene acquisition?
Transgenic crops acquire genes through artificial insertion.
Which term is commonly used to describe plants that contain transgenes?
Genetically modified (GM) crops
What process contributes to all crops becoming genetically modified over time, even without artificial insertion of genes?
Domestication, selection, and controlled breeding
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.
Test your knowledge on transgenic crops that contain artificially inserted genes from other species. Learn about genetically modified (GM) crops and their characteristics.
