Question

Golden rice is a genetically modified crop plant where the incorporated gene is meant for the biosynthesis of?

• A. Vitamin A
• B. Vitamin B
• C. Vitamin C
• D. Omega 3

Answer 1

The correct option is A

Vitamin A

The correct option is A.

Explanation for correct option:

1. Golden rice is a genetically engineered agricultural plant with a gene that is responsible for Vitamin A production.
2. It's high in beta carotene, which means it's a good source of vitamin A.
3. The rice variety is utilized to make the modified Oryza sativa.

Explanation for incorrect options:

Option B:

1. The golden rice gene doesn't produce Vitamin B.
2. A slight increase in vitamin B12 production is caused by cobU and cobS genes.

Option C:

1. The golden rice gene doesn't produce Vitamin C.
2. The inability to synthesize vitamin C is caused by a mutation in the L-gulono-γ-lactone oxidase (GLO) gene.
3. GLO codes for the enzyme that catalyzes the final step of the process.

Option D:

1. The golden rice gene doesn't produce Vitamin D as well.
2. The VDR gene contributes to the production of a protein called the vitamin D receptor (VDR), which is responsible for the body's response to vitamin D.

Final answer: Golden rice has a gene that is responsible for producing Vitamin A.
