Many eukaryotic genes (most human genes) are split; non-coding introns must be removed and the exons spliced together to make a mature mRNA. Introns are “intervening” sequences in genes that do not code for proteins.

WebGenes and Chromosomes. Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body.
