Question

Golden rice – a transgenic variety of rice is principally richer than normal rice in?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
**Primary Concept**: Biofortification and Genetic Engineering
**Related Topics**: Transgenic plants, Vitamin A deficiency, Plant breeding
**Prerequisites**: Basic knowledge of genetically modified crops and vitamins
## SOLUTION PATHWAY
**Given Information**:
        The question asks about the nutritional enrichment of Golden Rice.
**Method & Steps**:
1. Recall that Golden Rice is specifically engineered to produce beta-carotene, a precursor to Vitamin A.
Reasoning: This is a direct recall of a specific fact about Golden Rice.
2. Identify the correct option that lists beta-carotene.
Result: Option D is the correct answer.
## OPTION ANALYSIS
[A] :x: Cry I AB is a protein produced by Bacillus thuringiensis and is used as an insecticide, not a nutrient in Golden Rice.
[B] :x: Hirudin is an anticoagulant protein found in leeches, not related to Golden Rice's nutrient profile.
[C] :x: TPA (Tissue Plasminogen Activator) is a protein involved in dissolving blood clots, not present in Golden Rice.
[D] ✓: Beta-carotene is the precursor to Vitamin A, and Golden Rice is engineered to produce it.
## LEARNING AIDS
**Common Mistakes**:
1. Confusing Golden Rice with other genetically modified crops: Remember the specific purpose of Golden Rice is to produce beta-carotene.
2. Not knowing the functions of the other options: Understanding what each option represents helps in eliminating incorrect answers.
**Quick Tips**:
1. Associate Golden Rice with Vitamin A enrichment.
2. Use process of elimination if unsure of the answer.
