5. Would the exons of DNA normally ever be together as a separate DNA molecule in a cell without the introns as they were in the shorter sequence you used to find the exons and introns?

Explanation:
Introns and exons are nucleotide sequences within a gene. Introns are removed by RNA splicing as RNA matures, meaning that they are not expressed in the final messenger RNA (mRNA) product, while exons go on to be covalently bonded to one another in order to create mature mRNA.
Introns can be considered as intervening sequences, and exons as expressed sequences.
