Answer: (A) It is Vitamin A enriched, with a gene from daffodil. Answer: (A) It is Vitamin A enriched, with a gene from daffodil Solution: Golden rice is a genetically modified rice with enhanced nutritional value, engineered to be enriched in pro-vitamin A (beta-carotene).
- A.It is Vitamin A enriched, with a gene from daffodil✓
- B.It is pest resistant, with a gene from Bacillus thuringiensis
- C.It is drought tolerant, developed using Agrobacterium vector
- D.It has yellow grains, because of a gene introduced from a primitive variety of rice
Correct Answer
(A) It is Vitamin A enriched, with a gene from daffodil
Solution & Explanation
Answer: (A) It is Vitamin A enriched, with a gene from daffodil Solution: Golden rice is a genetically modified rice with enhanced nutritional value, engineered to be enriched in pro-vitamin A (beta-carotene). The biosynthesis genes were introduced from daffodil (and a bacterium), making it Vitamin 'A' enriched rice. It is not a pest-resistant Bt crop, nor drought-tolerant, and the colour is due to introduced carotenoid genes, not a primitive rice variety.
