Explanation:
Exon is a part of gene that encodes for final mature RNA after processing. In the process of RNA splicing, introns are removed and exons are retained and joined to produce mature mRNA.
They have protein coding sequence and also UTR ( Untranslated Region ) which plays a role in translation termination and post transcriptional gene expression. Human genome has only 1.1% exon and is majorly composed of introns and intergenic DNA.
