Transcription takes place in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells.

Quick scoop

  • In eukaryotes (like human, plant, or animal cells), DNA is stored in the nucleus, so transcription happens in the nucleus where RNA polymerase copies a gene into mRNA.
  • In prokaryotes (like bacteria), there is no nucleus, so transcription occurs directly in the cytoplasm , often while translation is already starting on the same mRNA.

Mini‑section: eukaryotes vs prokaryotes

Cell type| Where transcription happens| Why?
---|---|---
Eukaryotic| Nucleus 158| DNA is enclosed in the nucleus; mRNA is processed there before export to the cytoplasm for translation.
Prokaryotic| Cytoplasm 38| No nucleus; DNA floats in the cytoplasm, so transcription and translation can overlap spatially and temporally.

Trending‑style note

On forums and study‑help sites in 2025–2026, this question still pops up in biology threads, with students mixing up transcription (DNA → RNA) and translation (RNA → protein). Just remember:

  • Transcription = nucleus (eukaryotes) or cytoplasm (prokaryotes).
  • Translation = cytoplasm on ribosomes, in both types.
