The Central Dogma in prokaryotic versus eukaryotic cells In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All of these processes form part of the central dogma of molecular biology, which describes the flow of genetic information in a biological system. In eukaryotes, one mRNA = one protein. However, unlike replication, only one DNA strand is copied to RNA in transcription. The transcription and translation occurs only in the cytoplasm. 2. by the absence of a nuclear membrane, DNA Transcription Central Dogma: Genetic material is always nucleic acid and it is always DNA except some viruses. ; The mRNA is translated to a polypeptide sequence (a protein).
