Here are three key differences between DNA and RNA, including the specific base that differs:
1. **Structure**:
- **DNA (Deoxyribonucleic Acid)**: DNA is typically double-stranded, forming a double helix structure.
- **RNA (Ribonucleic Acid)**: RNA is usually single-stranded and can have a more varied structure.
2. **Sugar Component**:
- **DNA**: The sugar in DNA is deoxyribose, which lacks one oxygen atom compared to ribose.
- **RNA**: The sugar in RNA is ribose, which has an additional hydroxyl (-OH) group.
3. **Nitrogenous Bases**:
- **DNA**: The bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).
- **RNA**: The bases in RNA are adenine (A), uracil (U), cytosine (C), and guanine (G).
- **Key Difference**: The base that differs between DNA and RNA is thymine (T) in DNA, which is replaced by uracil (U) in RNA.
