in the cytoplasm in eukaryotes and the nucleus in prokaryotes

Detailed explanation-1: -With the genes bound in the nucleus, transcription occurs in the nucleus of the cell and the mRNA transcript must be transported to the cytoplasm. The prokaryotes, which include bacteria and archaea, lack membrane-bound nuclei and other organelles, and transcription occurs in the cytoplasm of the cell.
Detailed explanation-2: -Prokaryotic transcription occurs in the cytoplasm alongside translation. Prokaryotic transcription and translation can occur simultaneously. This is impossible in eukaryotes, where transcription occurs in a membrane-bound nucleus while translation occurs outside the nucleus in the cytoplasm.
Detailed explanation-3: -Thus, in eukaryotes, while transcription occurs in the nucleus, translation occurs in the cytoplasm.
Detailed explanation-4: -Transcription takes place in the cytoplasm in prokaryotes.
