I want to know the answer to the following question:
What bacteria is an exception to single circular chromosome rule?
All the background I'm provided with is that "Most bacteria have a single circular chromosome that can range in size from only 160,000 base pairs in the endosymbiotic bacteria Candidatus Carsonella ruddii, to 12,200,000 base pairs in the soil-dwelling bacteria Sorangium cellulosum.". Is that enough to answer the question?
Answer: no
