exon
Quick Summary
An exon is a segment of a nucleic acid, such as DNA or RNA, that contains genetic information essential for protein synthesis. These sequences are copied and then joined together to form messenger RNA (mRNA). In eukaryotes, after transcription, non-coding regions called introns are removed from the RNA molecule, and the remaining coding regions, the exons, are spliced together to create mature mRNA. The exome specifically refers to the complete set of exons within an organism's genome, representing the portion that codes for proteins. This process is fundamental to gene expression, where the genetic code is translated into proteins that determine an organism's traits and functions.1234

Phillip A. Sharp…coded for proteins, now called exons, were separated by long stretches of DNA, now called introns, that did not contain genetic information. At the same time, a team working independently under Roberts came up with the same finding. Previously biologists had believed that genes were continuous stretches of DNA that…
