The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Bacterial Chromosomes**: Bacterial chromosomes are different from eukaryotic chromosomes. Bacteria are prokaryotic organisms, meaning they lack a defined nucleus and their genetic material is not enclosed within a membrane. 2. **Structure of Bacterial DNA**: In bacteria, the DNA is typically organized into a single circular chromosome. This circular DNA is approximately 4 to 5 megabases (Mb) in length. 3. **Chromosome Packing in Bacteria**: Unlike eukaryotic cells, which utilize histone proteins to package their DNA, bacteria do not have histones. Instead, they use different proteins to help in the organization and packing of their DNA. 4. **Role of Acidic Proteins**: In bacterial cells, the packing of the circular chromosome is facilitated by acidic proteins. These proteins help to condense and organize the DNA within the bacterial cell. 5. **Conclusion**: Therefore, the genes in bacterial chromosomes are packed by acidic proteins. **Final Answer**: Genes are packed in bacterial chromosomes by acidic proteins. ---
