Transgenic models can be used to investigate several human diseases such as

Options

A. Alzheimer`s disease
B. Cystic fibrosis
C. Carcinoma
D. All of these

Answer

To answer the question regarding which human diseases can be investigated using transgenic models, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Transgenic Models**: Transgenic models refer to genetically modified organisms, typically animals, that have had genes from another species inserted into their genome. These models are used to study the effects of specific genes on disease development.

2. **Identifying Human Diseases**: Various human diseases can be modeled using transgenic animals. The purpose is to understand the genetic contributions to these diseases and to test potential treatments.

3. **Listing Common Diseases Studied**:
- **Cancer**: Transgenic models are used to study different types of cancer, including breast cancer and lung cancer.
- **Cystic Fibrosis**: This genetic disorder affects the lungs and digestive system, and transgenic models help in understanding its pathology and potential treatments.
- **Rheumatoid Arthritis**: This autoimmune disease can be studied in transgenic models to explore its mechanisms and therapies.
- **Alzheimer's Disease**: Transgenic mice are often used to study the progression of Alzheimer's and to test new drugs aimed at slowing its effects.

4. **Examples of Transgenic Models**:
- Transgenic mice are commonly used in research. They can be engineered to express human genes associated with diseases, allowing researchers to observe the effects of these genes in a living organism.

5. **Conclusion**: Based on the above points, transgenic models can be used to investigate several human diseases, including cancer, cystic fibrosis, rheumatoid arthritis, and Alzheimer's disease.

### Final Answer:
Transgenic models can be used to investigate several human diseases such as cancer, cystic fibrosis, rheumatoid arthritis, and Alzheimer's disease.
