16. A genetic deletion of the gene encoding the structural protein Emerin causes a severe disruption in the nuclear envelope layout by destabilizing the

A. Attachment of the nuclear lamina to the inner nuclear membrane
✓
B. Synthesis of rRNA in the nucleolus core
C. Export of tRNA through the pore complex
D. Continuity between the ER and outer membrane

📝 Explanation

Emerin is a vital inner nuclear membrane protein that anchors the nuclear lamina. Its loss disrupts nuclear structure, causing Emery-Dreifuss muscular dystrophy.

📖 Additional Information

  • Attachment of the nuclear lamina to the inner nuclear membrane
  • Synthesis of rRNA in the nucleolus core
  • Export of tRNA through the pore complex
  • Continuity between the ER and outer membrane
