Detailed explanation-1: -DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.
Detailed explanation-2: -In eukaryotes, as DNA is present inside the nucleus, DNA replication takes place inside the nucleus. Whereas in Prokaryotes, no well-developed nucleus is found. Also, no nuclear separation is seen due to the lack of a nuclear membrane. Hence, in prokaryotes, cytoplasm occurs.
Detailed explanation-3: -The final step is called translation, which involves the conversion of mRNA to protein. DNA replication and transcription occur inside the nucleus because the enzymes required to carry out these processes are found in the nucleoplasm.
