It is established that RNA is the first genetic material. Explain giving three reasons.

Explanation

**Step-by-Step Solution:**

1. **Introduction to Genetic Material**:
- Genetic material is essential for storing and transmitting hereditary information in living organisms. While DNA (deoxyribonucleic acid) is the primary genetic material in most organisms today, it is believed that RNA (ribonucleic acid) was the first genetic material.

2. **Reason 1: Chemical Reactivity of RNA**:
- RNA is chemically more reactive than DNA due to its structure. RNA contains an additional hydroxyl (OH) group on the ribose sugar, which makes it less stable and more prone to reactions. This reactivity allows for greater variation and adaptability, which is crucial for the evolution of life.
