WebWhy do prokaryotes not undergo meiosis? No, prokaryotes do not undergo mitosis or meiosis. Prokaryotic cells divide by binary fission. It is similar to mitosis, which requires replication of DNA and then equal division of genetic material and cytoplasm, to form two daughter cells. It is the asexual mode of reproduction in prokaryotic cells. WebFinally, prokaryotes have a handful of specialized RNAs that are absent from eukaryotes. These include the 6S RNA that regulates transcription and the tmRNA that rescues stalled ribosomes. In addition, riboswitches, located at the 5′-end of the mRNA, are typical of prokaryotes but extremely rare in eukaryotes.
