Which statement is correct about golden rice? I. Golden rice is a genetically modified variety of rice. II. It contains a substantial amount of β-carotene, which serves as a provitamin-A precursor. III. β-carotene is a primary source of vitamin B. IV. The grains of golden rice have a greenish color due to the presence of β-carotene. |
I, II, III and IV I, III and IV II, III and IV I and II |
I and II |
The correct answer is Option (4) -I and II Golden rice is a genetically modified variety of rice that has been developed to address vitamin A deficiency, which is a widespread health issue in many developing countries. The genetic modification involves introducing foreign genes into the rice plant. The inserted genes enable the rice plant to produce β-carotene, a pigment responsible for the yellowish-golden color in certain fruits and vegetables. β-carotene is a provitamin-A compound, meaning it can be converted into active vitamin A by the human body. With the introduction of β-carotene through genetic modification, golden rice becomes a valuable source of provitamin A, providing a potential solution to combat vitamin A deficiency in affected populations. By consuming golden rice, individuals can receive an additional dietary source of provitamin A, helping to improve overall health and nutrition. Golden rice has been a subject of both scientific and ethical discussions. While it offers a promising solution to address vitamin A deficiency, concerns have been raised about genetically modified crops, including potential environmental impacts, intellectual property issues, and social and cultural considerations. Nonetheless, the development of golden rice remains a significant advancement in the field of genetic engineering and biotechnology, aiming to contribute to global food security and improve public health. |
