- AIt is Vitamin A enriched, with a gene from daffodil
- BIt is pest resistance with a gene from Bacillus thuringiensis
- CIt is drought tolerant, developed using Agrobacterium vector
- DIt 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
Step-by-step solution
Golden rice is vitamin ‘A’ enriched rice it is generically modified to enhance nutritional value of food. Golden rice a variety of Oryza sativa is produced through the genetic engineering to biosynthesize beta-carotene, a precursor of pro-vitamin A in the edible parts of rice. Golden rice is enriched by introducing three genes involved in the biosynthetic pathway for carotenoid. Thus golden rice is genetically engineered rice with greater vitamin A content.
