Exons are regions of DNA that are transcribed to RNA and retained after introns are spliced out. However, the term “exon” is often misused as synonymous to “protein coding,” including in some literature and textbook definitions. In contrast, only a fraction of exonic sequences are protein coding (<30% in humans). how to download virtual pinball tables
