Yes, bacteria have ribosomes.
Bacteria, like all living organisms, need to synthesize proteins to carry out essential functions. Ribosomes are the cellular organelles responsible for protein synthesis. According to the provided reference, "bacteria need ribosomes in order to make proteins".
Ribosomes in Bacteria: Key Features
- Essential for Protein Synthesis: Ribosomes are critical for translating genetic information (mRNA) into functional proteins.
- Ubiquitous Organelles: They are found in all living cells, including bacteria.
- Target for Antibiotics: Bacterial ribosomes are structurally different from eukaryotic ribosomes, making them targets for certain antibiotics that can selectively inhibit bacterial protein synthesis without harming the host.
Comparison with Eukaryotic Ribosomes
| Feature | Bacterial Ribosomes | Eukaryotic Ribosomes |
|---|---|---|
| Size | 70S | 80S |
| Subunits | 30S and 50S | 40S and 60S |
| Antibiotic Target | Yes | Less often |
