Split genes have both exons and introns, but only the exons are initially transcribed to mRNA. Spliceosomes are required to excise the introns and join the exons together to produce the final mRNA transcript. Split genes are found in eukaryotes, but not in prokaryotes. Introns can be located throughout the coding region, not just at the beginning and end.
