Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Rice is the common diet in many developing countries, but is low in nutritional value. Which one of these biotechnologies could be the best option in creating a more nutritional rice?

A	selective breeding of current rice plants
B	cloning of current rice plants
C	using a nitrogen rich fertilizer
D	genetic modification of current rice plants

Explanation:

Detailed explanation-1: -Pre-treatment such as germination or water-soaking may improve both sensory qualities and nutritional values of brown rice. In China, brown rice of black rice varieties is generally consumed as rice soup (“congee”) instead of steamed rice.

Detailed explanation-2: -Golden rice is genetically modified to produce beta-carotene, which is not normally present in rice. Beta-carotene is converted into vitamin A when metabolized by the human body. We need vitamin A for healthier skin, immune systems, and vision.

Detailed explanation-3: -Conclusion: -Carotene derived from Golden Rice is effectively converted to vitamin A in humans.

Detailed explanation-4: -"Golden Rice” is a variety of rice engineered to produce beta-carotene (pro-vitamin A) to help combat vitamin A deficiency, and it has been predicted that its contribution to alleviating vitamin A deficiency would be substantially improved through even higher beta-carotene content.
