B2.2.2—Nucleus-cytoplasm separation Topic Practice
B2.2.2—Nucleus-cytoplasm separation Topic Practice
Students practise explaining how nuclear compartmentalisation enables eukaryotic gene regulation—especially via pre-mRNA splicing and nuclear pore selectivity.
How this is tested
- explain why RNA splicing must occur before mRNA export through nuclear pores
- relate nuclear envelope integrity to separation of transcription (nucleus) and translation (cytoplasm)
