[Campbell Biology P.405] Which of the following sequences correctly describes the major step... | Practice Question

Which of the following sequences correctly describes the major steps of gene expression in a eukaryotic cell and their respective locations, as depicted in the diagram?

  • A: Transcription (Cytoplasm) → RNA Processing (Nucleus) → Translation (Cytoplasm)
  • B: Transcription (Nucleus) → RNA Processing (Nucleus) → Translation (Cytoplasm)
  • C: RNA Processing (Cytoplasm) → Transcription (Nucleus) → Translation (Nucleus)
  • D: Translation (Cytoplasm) → Transcription (Nucleus) → RNA Processing (Cytoplasm)

Explanation

In eukaryotic gene expression, transcription occurs in the nucleus, followed by RNA processing splicing, 5' cap, poly-A tail addition also in the nucleus. The processed mRNA then moves to the cytoplasm for translation.
