Name the three Domains of organisms proposed by Woese.

Explanation

**Step-by-Step Solution:**

1. **Introduction to the Three Domains**: The three domains of organisms were proposed by Carl Woese and his colleagues in 1977. This classification system is based on differences in the 16S ribosomal RNA (rRNA) sequences.

2. **Understanding the Domains**: The three domains are:
- **Bacteria**: This domain includes all true bacteria, which can be beneficial or pathogenic to humans.
- **Archaea**: This domain consists of prokaryotic organisms that often live in extreme environments (extremophiles) and have distinct biochemical and genetic properties compared to bacteria.
- **Eukarya**: This domain encompasses all eukaryotic organisms, including protists, fungi, plants, and animals.
