Genetic Engineering Exam Questionsand Answers
What is genetic engineering? - Answer-Genetic engineering is the process which
involves modifying the genome of an organism by introducing a gene from another
organism to give a desired characteristic.
Insecticides are chemicals which kill insects.
Insecticides may be sprayed onto crops to increase crop yield.
Killing crops on yield may increase crop yield. Explain why? - Answer-Insects don't eat
or damage crops, increasing yield.
Give an example of use for genetically modified crops: - Answer-- Disease resistance
- Produce larger fruits
- Resistance to herbicides. This means farmers can spray their fields to kill weeds
without harming GM crops.
Some people are concerned about the use of GM crops.
Why? - Answer-They are concerned about:
- The effect of population of wide flowers
- Effect of eating GM crops on human health.
What is a use for genetically modified bacteria cells? - Answer-To produce human
insulin to treat diabetes.
Describe how scientists produce genetically modified zebra fish. - Answer-Jellyfish gene
is cut out using restriction enzymes.
Gene transferred to zebra stage at an early stage of development.
Some scientists are worried about the production of genetically modified zebra fish.
Suggest reasons why? - Answer-- Could transfer genes to other species
- Effects on food chains
- Effects on zebra fish themselves, E.g. may complete out non GM zebra fish.
What are vectors and what they used for? - Answer-Vectors are usually plasmids or
viruses and are used to insert genes into cells.
Scientists have genetically engineered a variety of wheat to be resistant to herbicides.
The herbicides resistant variety of wheat will give a higher yield than the non-herbicide
resistant variety. Explain Why. - Answer-Wheat are not affected by spraying herbicides,
only weeds are affected. Wheat will get more light, mineral ions so more
photosynthesis, therefore more glucose, therefore more proteins for more yield.
