Genetically modified (GM) crops contain modified genetic material due to :
1. introduction of new DNA
2. removal of existing DNA 3. introduction of RNA 4. introduction of new traits Select the correct answer using the code given below [CDS I 2016]
1) 1 and 2 only
2) 1, 2 and 3
3) 3 and 4
4) 1, 2 and 4
4) 1, 2 and 4
When the DNA of a plant had been modified using genetic engineering methods, it is called Genetically modified crops.
• It is widely used to make crops resistant to certain pests and disease.
• It is also used to improve nutrition value in a crop.
• Insect-resistant crops contain genes from the soil bacterium Bacillus thuringiensis.
• GM crops are sometimes discouraged to consume due to the following potential threats: an allergic reaction (allergenicity), gene transfer and outcrossing.
Genetically modified (GM) crops contain modified genetic material due to introduction of DNA by removing the existing DNA, resulting in the change in traits.
