Practice questions

In a eukaryotic cell, researchers isolate nuclear RNA from a gene containing three exons separated by two introns. A newly synthesized transcript is detected that hybridizes to probes complementary to exon 1, intron 1, exon 2, intron 2, and exon 3. After 10 minutes, the predominant nuclear RNA hybridizes only to exon probes, and sequencing shows exon 1 directly joined to exon 2 and exon 2 joined to exon 3. No changes are detected in the DNA sequence of the gene. Which explanation best accounts for the change in hybridization pattern over time?
