Detailed explanation-1: -Instead, the chromosome of a prokaryote is found in a part of the cytoplasm called a nucleoid. Prokaryotes generally have a single circular chromosome that occupies a region of the cytoplasm called a nucleoid.

Detailed explanation-2: -Most prokaryotic cells have just one chromosome, so they are classified as haploid cells (1n, without paired chromosomes). Even in Vibrio cholerae, which has two chromosomes, the chromosomes are unique from one another.

Detailed explanation-3: -While most prokaryotes, like E. coli, contain a single circular DNA molecule that makes up their entire genome, recent studies have indicated that some prokaryotes contain as many as four linear or circular chromosomes. For example, Vibrio cholerae, the bacteria that causes cholera, contains two circular chromosomes.

Detailed explanation-4: -Many prokaryotes also carry small, circular DNA molecules called plasmids, which are distinct from the chromosomal DNA and can provide genetic advantages in specific environments.

Detailed explanation-5: -Prokaryotes have circular DNA while eukaryotes have linear chromosomes.
