Detailed explanation-1: -The nucleoid region is an irregular-shaped section of the cytoplasm that contains prokaryotic DNA. Unlike the nucleus of a eukaryotic cell, this region does not have a nuclear membrane. Instead, prokaryotic cells keep their chromosomes along with their ribosomal RNA molecules in direct contact with the cytoplasm.

Detailed explanation-2: -By definition, prokaryotes lack a membrane-bound nucleus to hold their chromosomes. 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.
