Mesosomes are characteristic of prokaryotic Bblbepute onuH OTBeT: a. Ribosomes b. Cell membrane c. Nucleoid d. Cell wall

The correct answer is c. Nucleoid.<br /><br />Mesosomes are characteristic of prokaryotic cells and are associated with the nucleoid region, which is the region where the genetic material (DNA) is located in prokaryotic cells. The nucleoid is not surrounded by a membrane, unlike the nucleus in eukaryotic cells. Mesosomes are invaginations of the plasma membrane that help in the organization of the DNA and other cellular processes.
