DNA is genetic material because

Options

A. It has capacity material to replicate
B. It is chemically and structurally stable
C. It provide scope for slow mutations
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of DNA**:
- DNA is recognized as the genetic material in living organisms. This is primarily due to its ability to store and transmit genetic information.

2. **Self-Replication**:
- One of the key features of DNA is its ability to replicate itself. This means that when a cell divides, DNA can make copies of itself to ensure that each new cell has the same genetic information.

3. **Chemical Stability**:
- DNA is chemically more stable than RNA. This stability is attributed to its structure, which includes deoxyribose sugar and the presence of thymine instead of uracil (which is found in RNA). The stability of DNA allows it to maintain genetic information over long periods.

4. **Low Mutation Rate**:
- DNA has a low mutation rate compared to RNA. This is crucial because mutations can lead to errors in genetic information. The efficient repair mechanisms in DNA help correct any potential mutations, ensuring the integrity of the genetic material.

5. **Comparison with RNA**:
- RNA, while also capable of carrying genetic information, is less stable and has a higher mutation rate. This makes DNA a more reliable form of genetic material for long-term information storage.

6. **Conclusion**:
- Given these points, DNA is considered the genetic material because it can replicate itself, is chemically and structurally stable, and has a low mutation rate due to efficient repair mechanisms. Therefore, all these factors contribute to DNA being the primary genetic material in organisms.

**Final Answer**: DNA is genetic material because:
- It has the capacity to replicate.
- It is chemically and structurally stable.
- It provides scope for slow or less mutation due to efficient repair mechanisms.
- Thus, all of these factors make DNA the genetic material.
