In eukaryotic cells, transcription occurs primarily in which cellular compartment?

Nucleus.

Transcription in eukaryotic cells occurs in the nucleus. DNA resides there, and the RNA polymerases transcribe nuclear genes into pre-mRNA inside this compartment. This transcript then undergoes processing—capping, splicing, and polyadenylation—before being exported to the cytoplasm for translation on ribosomes. While mitochondria have their own genomes and can transcribe within the organelle, most transcription throughout the cell happens in the nucleus. Hence, the nucleus is the primary site of transcription.

Cytoplasm.

Mitochondria.

Ribosome.
