What is the primary objective of developing Golden Rice?

  1. To enhance the nutritional value of rice

  2. To increase rice yield in drought-prone areas

  3. To reduce the cost of rice production

  4. To create a new variety of rice with unique flavors


Correct Option: A
Explanation:

Golden Rice is genetically modified to produce beta-carotene, a precursor of vitamin A, to address vitamin A deficiency, a prevalent issue in many regions.

Which nutrient is enhanced in Golden Rice?

  1. Vitamin A

  2. Vitamin C

  3. Vitamin D

  4. Vitamin E


Correct Option: A
Explanation:

Golden Rice is engineered to produce beta-carotene, which is converted into vitamin A in the human body, addressing vitamin A deficiency.

How does Golden Rice address vitamin A deficiency?

  1. By directly providing vitamin A

  2. By producing beta-carotene, which is converted to vitamin A in the body

  3. By increasing the absorption of vitamin A from other food sources

  4. By reducing the need for vitamin A supplements


Correct Option: B
Explanation:

Golden Rice contains beta-carotene, which is converted into vitamin A in the human body, providing a dietary source of this essential nutrient.

What is the primary genetic modification made to Golden Rice?

  1. Insertion of a gene encoding beta-carotene biosynthesis

  2. Removal of genes responsible for allergenic proteins

  3. Modification of genes to increase yield

  4. Transfer of genes from other plant species


Correct Option: A
Explanation:

Golden Rice is modified by inserting a gene that encodes beta-carotene biosynthesis, allowing the rice plant to produce beta-carotene, which is converted to vitamin A in the human body.

Which organization played a significant role in developing Golden Rice?

  1. International Rice Research Institute (IRRI)

  2. World Health Organization (WHO)

  3. Food and Agriculture Organization (FAO)

  4. United States Department of Agriculture (USDA)


Correct Option: A
Explanation:

The International Rice Research Institute (IRRI) played a leading role in developing Golden Rice, conducting research and collaborating with other institutions to bring the project to fruition.

What is the primary color of Golden Rice?

  1. Golden yellow

  2. Bright orange

  3. Deep red

  4. Natural white


Correct Option: A
Explanation:

Golden Rice is characterized by its golden yellow color, which is derived from the accumulation of beta-carotene in the rice grains.

Which country was the first to approve the commercial cultivation of Golden Rice?

  1. Philippines

  2. Bangladesh

  3. India

  4. China


Correct Option: A
Explanation:

The Philippines was the first country to approve the commercial cultivation of Golden Rice in 2021, marking a significant milestone in the fight against vitamin A deficiency.

What is the primary target population for Golden Rice?

  1. People living in vitamin A-deficient regions

  2. Athletes and fitness enthusiasts

  3. People with specific dietary restrictions

  4. Children and adolescents


Correct Option: A
Explanation:

Golden Rice is primarily intended to benefit people living in regions where vitamin A deficiency is prevalent, particularly in developing countries.

Which vitamin A deficiency-related condition is Golden Rice designed to address?

  1. Night blindness

  2. Scurvy

  3. Rickets

  4. Pellagra


Correct Option: A
Explanation:

Golden Rice is specifically designed to address night blindness, a condition caused by vitamin A deficiency that impairs vision in dim light.

How does Golden Rice contribute to sustainable agriculture?

  1. By reducing the need for chemical fertilizers

  2. By increasing crop yield in marginal lands

  3. By promoting biodiversity in farming systems

  4. By reducing the use of pesticides


Correct Option: B
Explanation:

Golden Rice has the potential to increase crop yield in marginal lands, making it a valuable tool for sustainable agriculture and food security.

What is the main challenge associated with the commercialization of Golden Rice?

  1. High production costs

  2. Lack of consumer acceptance

  3. Regulatory hurdles

  4. Environmental concerns


Correct Option: C
Explanation:

Regulatory hurdles, including biosafety assessments and approval processes, pose a significant challenge to the commercialization of Golden Rice.

Which scientific technique is primarily used to modify Golden Rice?

  1. Genetic engineering

  2. Selective breeding

  3. Hybridization

  4. Tissue culture


Correct Option: A
Explanation:

Golden Rice is modified using genetic engineering techniques, which involve the precise insertion of genes into the rice genome.

What is the primary source of beta-carotene in Golden Rice?

  1. Corn

  2. Carrots

  3. Sweet potatoes

  4. Spinach


Correct Option: A
Explanation:

The beta-carotene in Golden Rice is derived from a gene introduced from corn, which naturally produces high levels of this nutrient.

Which organization is responsible for coordinating global efforts to combat vitamin A deficiency?

  1. World Health Organization (WHO)

  2. United Nations Children's Fund (UNICEF)

  3. Food and Agriculture Organization (FAO)

  4. Global Alliance for Improved Nutrition (GAIN)


Correct Option: D
Explanation:

The Global Alliance for Improved Nutrition (GAIN) is a public-private partnership that coordinates global efforts to combat vitamin A deficiency and other nutritional challenges.

What is the primary goal of the Golden Rice project?

  1. To eradicate vitamin A deficiency worldwide

  2. To increase rice production in developing countries

  3. To develop a new variety of rice with enhanced flavor

  4. To reduce the cost of rice cultivation


Correct Option: A
Explanation:

The Golden Rice project aims to eradicate vitamin A deficiency worldwide by providing a dietary source of this essential nutrient through genetically modified rice.
