Golden rice: Is a genetically modified

golden rice is a genetically modified crop plant where the incorporated gene. Golden rice is a variety of rice produced through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of rice . ' Golden rice ' has been genetically modified to meet human nutritional requirements. Which of the following statements correctly describes golden rice ? Rice produces carotene in the leaves but the biosynthetic pathway is turned off during plant development in grains. Transgenic rice , Golden Rice , was engineered by inserting two genes that restart the carotenoid biosynthetic pathway leading to the production and accumulation of carotene in the grains. These are the naturally occurring down-regulated genes. But the transgenic variety does not show down regulation and grains are rich in vitamin A. Golden rice is a transgenic variety of rice (Oryza Sativa) which contains good quantities of β-carotene ( provitamin A- inactive state of vitamin A). β-carotene is a principle source of vitamin A. Since the grains (seeds) of the rice are yellow in colour due to β-carotene, the rice is commonly called golden rice . Was this answer helpful?
