20. The spatial separation of transcription in the nucleus and translation in the cytoplasm provides eukaryotes with the unique ability to

A. Replicate DNA without histones
B. Perform extensive post-transcriptional RNA modification
✓
C. Generate ATP via oxidative phosphorylation
D. Synthesize proteins without ribosomes

📝 Explanation

Because mRNA is kept away from ribosomes during synthesis, the cell can safely carry out splicing and capping before protein translation starts.

📖 Additional Information

  • Replicate DNA without histones
  • Perform extensive post-transcriptional RNA modification
  • Generate ATP via oxidative phosphorylation
  • Synthesize proteins without ribosomes

Because mRNA is kept away from ribosomes during synthesis, the cell can safely carry out splicing and capping before protein translation starts.
