Which type of ribosomes are found in mitochondria?

Answer

**Step-by-Step Solution:**

1. **Identify the Location**: Mitochondria are organelles found in eukaryotic cells.

2. **Understand Ribosome Types**: Eukaryotic cells typically contain 80S ribosomes, which are composed of two subunits: 60S and 40S.

3. **Recognize Mitochondrial Ribosomes**: Despite being located in eukaryotic cells, the ribosomes found in mitochondria are not the typical eukaryotic ribosomes.

4. **Compare with Prokaryotic Ribosomes**: The ribosomes in mitochondria are similar to those found in prokaryotic cells, which have 70S ribosomes.

5. **Identify Subunits of Mitochondrial Ribosomes**: The 70S ribosomes in mitochondria consist of two subunits: 50S and 30S.

6. **Conclusion**: Therefore, the type of ribosomes found in mitochondria is 70S, which are similar to prokaryotic ribosomes.

**Final Answer**: The type of ribosomes found in mitochondria is 70S ribosomes.
