Read the RNA That Stays in the Nucleus
Some RNAs function inside the nucleus, where eukaryotic transcripts are processed before export.

Identify nuclear RNA
snRNA functions in the nucleus as part of the spliceosome, which removes introns and joins exons in pre-mRNA.
Interpret hybridisation loops
When mature mRNA hybridises to an uninterrupted bacterial gene, no loops appear because the gene lacks introns removed from the transcript.
OlympIQ exam lens
- ✓snRNA: nuclear splicing role.
- ✓Mature mRNA–gene loops indicate removed introns; no loops suggest an uninterrupted gene.
OlympIQ trap
Splicing removes introns, not exons.
