Question

Transgenic animals are used as model organisms to study human diseases. Which aspect makes them suitable for this purpose?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Transgenic animals as model organisms in disease research.
 **Related Topics**: Genetic engineering, animal models, human disease mechanisms.
 **Prerequisites**: Basic understanding of genetics and animal biology.
## SOLUTION PATHWAY
**Given Information**:
  Transgenic animals are used to study human diseases.
  Options describing various aspects of transgenic animals.
**Method & Steps**:
 1. Analyze each option to determine its relevance to using transgenic animals for disease research.
  Reasoning: We need to identify the characteristic that allows transgenic animals to effectively mimic human diseases.
  Formula/Rule: None directly applicable.
 2. Evaluate the suitability of each option based on the primary concept.
  Working:  Let's examine each option:
                A. Shorter lifespans are beneficial but not the primary reason for their use.
                B. Ease of maintenance is helpful, but not the defining characteristic.
                C. The ability to genetically modify animals to mimic human diseases is the core reason for their use as model organisms.
                D. Ethical considerations are important, but not the reason for their suitability as models.
 3. Select the option that directly addresses the suitability of transgenic animals as models for human diseases.
  Result: Option C accurately describes the key feature that makes transgenic animals suitable for studying human diseases.
  Verification: Transgenic technology allows scientists to introduce specific genetic mutations into animals, creating models that accurately reflect the genetic basis of many human diseases.
 ## OPTION ANALYSIS
A :x: Shorter lifespans can be advantageous in some cases but is not the primary reason for using transgenic animals in disease research.
B :x: Ease of maintenance is a practical consideration but not the defining factor in the suitability of transgenic animals as disease models.
C ✓: The ability to genetically modify animals to mimic human disease conditions is the crucial aspect that makes them valuable for research.  Scientists can introduce specific genes or mutations that cause the disease in humans, providing a model to study disease progression, treatment options, etc.
D :x: Ethical considerations are important in all animal research, but this doesn't explain why transgenic animals are *suitable* for modeling human diseases. 
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing ease of maintenance or shorter lifespan with the core reason for using transgenic animals.
  How to avoid: Focus on the central principle of genetic modification and its role in mimicking human diseases.
  2.Overlooking the importance of genetic manipulation in creating accurate models.
  How to avoid: Understand that genetic modification allows the creation of animals with specific disease-causing mutations.
 **Quick Tips**:
  1.Remember the key term “genetically modified” and its direct relevance to the question.
  2.Think about how genetic engineering enables the creation of disease models in animals.
