Why do genes work in other species?
Reveal answer
Universal genetic code.
Key words: universal
Example of a transgenic organism?
Reveal answer
Bacteria making human insulin.
Key words: insulin
What is meant by the term transgenic?
Reveal answer
Containing genetic material transferred from a different species.
Key words: transgenic
What is meant by the term transgene?
Reveal answer
A gene transferred from one species into another.
Key words: transgene
What is meant by the term genetic code?
Reveal answer
The way base sequences code for amino acids; shared by almost all organisms.
Key words: genetic code
Transgenic or not?, Bacterium making human insulin. Source of new genetic material? Transgenic??
Reveal answer
Source of new genetic material: Human (different species). Transgenic?: Yes.
Key words: Bacterium making human insulin
Transgenic or not?, Bt maize. Source of new genetic material? Transgenic??
Reveal answer
Source of new genetic material: Bacterium (different species). Transgenic?: Yes.
Key words: Bt maize
Transgenic or not?, High-yield wheat from selective breeding. Source of new genetic material? Transgenic??
Reveal answer
Source of new genetic material: Same species, normal breeding. Transgenic?: No.
Key words: High-yield wheat from selective breeding
True or false, and why? “All GM organisms are transgenic.”
Reveal answer
False. Only those with genetic material from a different species are transgenic.
True or false, and why? “Selectively bred organisms are transgenic.”
Reveal answer
False. Selective breeding uses alleles of the same species.
True or false, and why? “A transgenic organism becomes a new hybrid species.”
Reveal answer
False. It stays the same species with one or a few added genes.
Give an example of a transgenic plant.
Reveal answer
Bt maize (insect-resistant), golden rice or herbicide-resistant soya.
Key words: Bt maize
Give an example of a transgenic animal.
Reveal answer
A sheep or goat that makes a human protein in its milk.
Key words: milk
Suggest one concern people have about growing transgenic crops.
Reveal answer
The new gene could spread to wild plants in pollen; harm to other insects; unknown long-term effects (any one).
Key words: wild plants
