Describe the key differences in genetic material organization between prokaryotic and eukaryotic cells.

In prokaryotic cells, the genetic material (DNA) is typically a single circular chromosome located in the cytoplasm within a region called the nucleoid, without a surrounding membrane. Plasmids (small, circular DNA molecules) may also be present. In eukaryotic cells, the genetic material is organized into multiple linear chromosomes enclosed within a membrane-bound nucleus. Eukaryotic DNA is also associated with histone proteins, forming chromatin, which is further condensed into chromosomes during cell division.
