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 a genetically modified, biofortified crop. Biofortification increases the nutritional value of crops. Golden rice is genetically modified to produce beta-carotene, which is not normally present in rice. Beta-carotene is converted into vitamin A when metabolized by the human body.

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.
