Detailed explanation-1: -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-2: -DNA is found in the cytoplasm of prokaryotes.

Detailed explanation-3: -In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. In eukaryotes, however, the DNA takes the form of compact chromosomes separated from the rest of the cell by a nuclear membrane (also called a nuclear envelope).

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.
