Explanation:
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: -Prokaryotic cells do not have a nucleus. Instead, their DNA floats around inside the cell. Organisms with prokaryotic cells are called prokaryotes.
Detailed explanation-3: -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. They also may contain small rings of double-stranded extra-chromosomal DNA called plasmids.
