In eukaryotes, transcription occurs in the _______ where translation occurs in _______.

Explanation:
Transcription in eukaryotes happens in the nucleus, where DNA resides and RNA polymerase builds the pre-mRNA. The RNA must be processed (capping, splicing, polyadenylation) and then exported through nuclear pores to the cytoplasm, where ribosomes translate it into protein. Translation occurs in the cytoplasm (either in the cytosol or on the rough endoplasmic reticulum). This spatial separation is due to the nuclear envelope, which keeps transcription and RNA processing inside the nucleus while ribosomes operate in the cytoplasm. If transcription occurred in the cytoplasm or translation in the nucleus, RNA processing or access by ribosomes would be hindered, disrupting gene expression.
