Question

Golden rice is rich in

• A. Vitamin A
• B. Vitamin B
• C. Vitamin C
• D. Vitamin K

Hint:

Golden Rice = Biofortification.
Beta-carotene $\rightarrow$ Yellow Color $\rightarrow$ Vitamin A.
Remember: Yellow/Orange vegetables (carrots, pumpkins) are usually rich in Vitamin A.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question asks to identify the specific nutrient that "Golden Rice," a genetically modified variety, is designed to provide in high quantities.
Detailed Explanation:

• Genetic Modification:
Golden Rice was engineered to synthesize beta-carotene in the edible part of the rice (the endosperm).
Beta-carotene is a provitamin; the human body converts it into Vitamin A (Retinol) upon consumption.

• The "Golden" Color:
The presence of beta-carotene gives the rice grains a characteristic golden-yellow color, which is why it is named "Golden Rice."

• Purpose:
It was developed to combat Vitamin A Deficiency (VAD) in developing countries, particularly in regions where rice is the staple food. VAD is a leading cause of childhood blindness and immune system failure.

• Creators:
It was developed by Ingo Potrykus and Peter Beyer in the late $1990$s.

Step 2: Final Answer:
Golden rice is biofortified and rich in beta-carotene, which is the precursor to Vitamin A.
