Which of the following best describes the structure of prokaryotic DNA?

Prokaryotic DNA is best described as circular and lacking histones. In prokaryotic cells, such as bacteria, DNA is organized in a single, circular molecule that is not compartmentalized within a nucleus, differentiating it from eukaryotic DNA, which is linear and associated with histones. The circular structure of prokaryotic DNA allows for efficient replication and expression, as it can be quickly copied during cell division. The absence of histones means that the DNA is not wrapped around these proteins, which is a characteristic of eukaryotic cells, where histones help to package DNA into a more compact form. This structural difference is crucial for understanding how prokaryotic organisms operate and replicate.
