Biofortification
Mediumbiology
Golden rice is engineered to provide increased levels of which nutrient precursor?
Select the correct option:
Solution
Incorrect! Answer:
Beta-carotene
- Objective: Biofortification involves breeding crops to increase their nutritional value.
- Engineering: Golden Rice is a variety of Oryza sativa produced through genetic engineering to biosynthesize Beta-carotene, a precursor of Vitamin A, in the edible parts of the rice.
- Public Health: It was developed as a potential solution to Vitamin A deficiency (VAD) in regions where rice is the staple food, which can lead to blindness and weakened immunity.
- Comparison: Iron fortification is done in other crops (e.g., Atlas 66 wheat), but not the primary focus of the 'Golden Rice' variety.
