Detailed explanation-1: -It is intended to produce a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A. Vitamin A deficiency causes xerophthalmia, a range of eye conditions from night blindness to more severe clinical outcomes such as keratomalacia and corneal scars, and permanent blindness.
Detailed explanation-2: -Golden Rice is developed through genetic engineering. While ordinary rice does produce beta carotene, it is not found in the grain. Thus, scientists used genetic engineering to add the compound to the grain-a minor tweak that improved the grain’s nutritive value.
Detailed explanation-3: -The ‘new’ property of Golden Rice, as a result of its colour, is nutrition: it contains beta-carotene (an important source of vitamin A) additional to the carbohydrate energy source of white rice, which is unchanged. Golden Rice is above all a well-being, a nutritional, a medical project.
Detailed explanation-4: -1. Which of the following describes scientists’ reasons for producing Golden Rice? To allow the rice to produce beta carotene and therefore vitamin C. Eating the rice will prevent vitamin C deficiencies that cause blindness and immune system problems.
