The following information is about Exon.
Exon Defined
A portion of a split gene that is included in the transcript of a gene and survives processing of the RNA to become part of the spliced messenger of a structural RNA. Exons generally occupy three distinct regions of genes that encode proteins. Exons in the first region are not translated into protein, but signal the beginning of RNA transcription and contain sequences that direct the mRNA to ribosomes for protein synthesis. Exons in the second region contain the information that is translated into the amino acid sequence of the protein, and are sometimes referred to as coding exons. Exons in the third region are transcribed into the part of the mRNA that contains the signals for the termination of translation and for the addition of a polyadenylate tail.
This definition is in context to Yeast Genome. See more contextual defintions for Exon.

- Protein Encoding Gene: This diagram focusses more on the step of creating the mRNA than the transcription or translation of protein syntheis, however the graph does label the location of promoters on DNA. The diagram shows how intons are not coded and are removed in the formation of mRNA while exons are only coded if they are within the open reading frame. Not shown on this diagram are the cap at the 5' end or the polyadenylatio n at the 3' end. This is relevant to the Biological Molecules (MB1001) module.
