Question

Which of the following is true for golden rice?

• A. It has yellow grains, due to a gene introduced from a primitive rice variety.
• B. It is vitamin A enriched, with a gene from daffodil.
• C. It is pest resistant, with a gene from Bacillus thuringiensis.
• D. It is drought tolerant, developed using Agrobacterium vector.

Answer 1

The correct option is B It is vitamin A enriched, with a gene from daffodil.

Golden rice (Oryza sativa ) is a variety of rice produced by introducing the psy gene from daffodil into the genome of normal rice enabling it to biosynthesize beta-carotene, a precursor of vitamin A. Hence, it can help to eliminate vitamin A deficiency.
