UPSC 2010: Genetically modified “golden rice” has been engineered to meet human nutritional requirements. Which one of the following statements best qualifies golden rice?
(a)The grains have been fortified with genes to provide three times higher grain yield per acre than other high yielding varieties
(b)Its grains contain pro-vitamin A which upon ingestion is converted to vitamin A in the human body
(c)Its modified genes cause the synthesis of all the nine essential amino acids
(d)Its modified genes cause the fortification of its grains with vitamin D
Attempt This Question
Not attemptedCorrect Answer: (b) Its grains contain pro-vitamin A which upon ingestion is converted to vitamin A in the human body
Golden rice has been engineered with phytoene synthase and phytoene desaturase genes so that its endosperm synthesises β-carotene (pro-vitamin A); this carotenoid is converted to vitamin A after consumption, addressing vitamin-A deficiency. It does not boost yield, amino-acid profile or vitamin D content.
