Here is a question about this article: The transcribed pre-mRNA contains untranslated regions at both ends which contain a ribosome binding site, terminator and start and stop codons.

The sequences at the ends of the introns, dictate the splice sites to generate the final mature mRNA which encodes the protein or RNA product.
What is the answer to this question: What dictates the splice sites to generate the final mature mRNA?

So... The sequences at the ends of the introns
