Q.

Golden rice is a genetically modified crop plant where the incorporated gene is meant for biosynthesis of Vitamin A. Golden rice has enhanced nutritional value.In this case two genes are introduced from daffodils (Narcissus- plant) and the third one from the soil bacteria  Erwinia uredovora. Genes are inserted in edible parts of rice to produce beta-carotene which further produces pro-vitamin A. This rice has 23 times more beta-carotene than the original rice.
