Alternative splicing is a process in eukaryotes where a single gene can lead to multiple proteins by including or excluding certain sequences of RNA. The Lac operon is a prokaryotic gene regulation mechanism and does not involve alternative splicing. Both the Troponin T gene in rats and the Sex-lethal (Sxl) gene in Drosophila are examples of alternative splicing in eukaryotes.
