Exons are the sequences coding for proteins that are present between either the untranslated regions or two introns. These are found only in eukaryotic genomes. These are found in both eukaryotic and prokaryotic genomes.

Where are exons and introns found?

Sequences that are joined together in the final mature RNA after RNA splicing are exons. Introns are found in the genes of most organisms and many viruses and can be located in a wide range of genes, including those that generate proteins, ribosomal RNA (rRNA) and transfer RNA (tRNA).
