The spliceosome is found in which type of organisms?

Explanation:
Splicing of pre-mRNA by the spliceosome is a process used to remove introns and join exons in the nucleus of eukaryotic cells. Prokaryotes generally don’t have introns and don’t rely on this complex for RNA processing, so they don’t possess the spliceosome. While some archaea have introns in their RNA genes, they don’t use the eukaryotic spliceosome mechanism. This reliance on a nucleus-based, snRNP-containing machinery to process introns is characteristic of eukaryotes, making them the correct context for spliceosome activity.
