Detailed explanation-1: -Golden rice is a variety of rice (Oryza sativa) produced through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of the rice. It is intended to produce a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A.

Detailed explanation-2: -Golden Rice is developed through genetic engineering. While ordinary rice does produce beta carotene, it is not found in the grain. Thus, scientists used genetic engineering to add the compound to the grain-a minor tweak that improved the grain’s nutritive value.

Detailed explanation-3: -Golden Rice is a good example of a biofortified crop. In this specific case biofortification was obtained by genetic modification of the rice plant to produce and accumulate provitamin A (-carotene) in the grain, something that doesn’t happen in naturally occurring rice plants.

Detailed explanation-4: -A specific variety of rice, golden rice, is genetically engineered with recombinant DNA to express enzymes that promote B-carotene biosynthesis.
