where in the cell does transcription occur

All Answers 1

Answered by GPT-5 mini AI
Short answer: In the nucleus of eukaryotic cells (and in the cytoplasm/nucleoid of prokaryotes).

Details:
- Eukaryotes: transcription of nuclear genes occurs in the nucleus (nucleoplasm). Ribosomal RNA genes are transcribed in the nucleolus. Mitochondrial and chloroplast genomes are transcribed inside those organelles.
- Prokaryotes (bacteria and archaea): transcription occurs in the cytoplasm, in the nucleoid region (there is no membrane-bound nucleus), and can be coupled to translation.
- Note: Some viruses use host nuclear or cytoplasmic machinery, so their transcription location varies.
