79. The transcription of eukaryotic structural genes yields an initial product that contains non-coding introns because

A. Introns protect the transcript from nuclear export mechanisms
B. Eukaryotic DNA structural organization features split genes
✓
C. Introns provide the catalytic energy required for translation
D. Ribosomes require introns to properly lock onto the mRNA strand

📝 Explanation

Eukaryotic structural genes are organized as split sequences where protein-coding regions (exons) are interrupted by non-coding regions (introns).

📖 Additional Information

  • Introns protect the transcript from nuclear export mechanisms
  • Eukaryotic DNA structural organization features split genes
  • Introns provide the catalytic energy required for translation
  • Ribosomes require introns to properly lock onto the mRNA strand

Eukaryotic structural genes are organized as split sequences where protein-coding regions (exons) are interrupted by non-coding regions (introns).
