Why does the bacterium Bacillus thuringiensis not affected by the toxins produced by it that can kill arthropods?
| 1. | The toxin inactivated by proteins in the bacterial cells. |
| 2. | The bacterial cell does not have organelles and thus it is harmless. |
| 3. | It is produced as a pro-toxin by the bacterium. |
| 4. | The protein needs post-transcriptional modification possible only in eukaryotic cells. |
