In most prokaryotes, the chromosome number is 1.

Prokaryotic organisms, such as bacteria and archaea, typically possess a single, circular chromosome located in a region called the nucleoid within the cytoplasm. Unlike eukaryotes, their genetic material is not enclosed within a membrane-bound nucleus and is usually present as one primary chromosome.

While most prokaryotes have one main circular chromosome, some may have linear chromosomes or additional smaller circular DNA molecules called plasmids. Eukaryotes, in contrast, have multiple linear chromosomes located within the nucleus.
