D)Transcription occurs in the nucleus.

Question

Quizplus · Accepted Answer

Transcription in eukaryotic cells occurs in the nucleus, which is a compartmentalized region of the cell that contains the DNA. Unlike prokaryotic cells, eukaryotic cells undergo extensive processing of their transcripts, such as RNA splicing and addition of a 5' cap and 3' poly-A tail. Additionally, eukaryotic mRNAs are typically monocistronic, meaning they encode for only one protein, whereas prokaryotic mRNAs are often polycistronic, encoding for multiple proteins. Finally, although transcription and translation occur simultaneously in prokaryotic cells due to their lack of compartmentalization, they are spatially separated in eukaryotic cells, with transcription occurring in the nucleus and translation occurring in the cytoplasm.
