The part of a gene that codes for amino acids is called an exon. Most gene sequences in plants and animals' cells are broken up by one or more DNA sequences known as introns. Exons are parts of the gene sequence that are expressed in the protein, whereas introns are regions of the gene sequence that are not expressed in the protein and come between or interfere with the exons. Now, when RNA is first transcribed, it is a very, very long RNA molecule. The exons are the most crucial sections of the RNA. There are huge portions of RNA that get cut out.
