State the differences between introns and exons.
Introns and exons are parts of genes - exons code for proteins, whereas introns do not, ie: exons are converted into messenger RNA to allow these parts of the gene to then be transcribed into protein. Introns are non protein coding regions and are removed in a process termed splicing by snRNPs.
