Detailed explanation-1: -Prokaryotic cells, such as bacteria, have a free-floating chromosome that is usually circular and is not enclosed in a nuclear membrane . Instead, the DNA simply exists in a region of the cell called the nucleoid.

Detailed explanation-2: -The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane. 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-3: -In eukaryotes, DNA is housed within the nucleus, but in prokaryotes, DNA is located directly within the cellular cytoplasm, as there is no nucleus available.

Detailed explanation-4: -Cytoplasm of prokaryotic cells Located within the cytoplasm of a prokaryotic cell is a single loop of DNA known as a nucleoid. The nucleoid is not membrane bound and suspends freely within the cytosol. Accompanying the nucleoid material of the prokaryotic cell is a small ring of extrachromosomal DNA known as plasmid.

Detailed explanation-5: -Interestingly, “prokaryote” means “before the nucleus, ” and refers to a cell structure where the chromosomal DNA is not enveloped in any internal membrane but is free in the cell cytoplasm.
