Where does transcription occur in a eukaryotic cell?

• A. In the Golgi apparatus by RNA polymerase.
• B. In the cytoplasm by DNA polymerase.
• C. In mitochondria by ribosomes.
• D. In the nucleus by RNA polymerase.

Answer: (D)

Transcription in eukaryotic cells happens in the nucleus, where the DNA is stored. RNA polymerase reads the DNA template and synthesizes a complementary RNA strand, which becomes mRNA after processing. This mRNA is then exported to the cytoplasm to be translated on ribosomes. The Golgi apparatus isn’t involved in transcription, and DNA polymerase copies DNA—not RNA. While mitochondria do carry out some transcription with their own machinery, the primary location for transcription of nuclear genes is the nucleus.
