ABOUT
A gene is one part of a genome. A genome is the collection of all the genes in a single organism. Each gene can be broken down into important parts: A promoter, coding region, and terminator.

Parts of a Gene
COPYRIGHT © 2014 JONATHAN TABB SULLIVAN
A gene is one part of a genome. A genome is the collection of all the genes in a single organism. Promoter: The promoter of a gene contains information about when to turn the gene on or off. Coding region: This is the part of the gene that gets "translated" into a protein. Most genes are translated into a protein, but not all. Terminator: The terminator is the signal that stops translation of the gene.
A gene is one part of a genome. A genome is the collection of all the genes in a single organism. In eukaryotic cells genes also contain introns and exons. Intron: Introns are genetic material that is translated into the final protein. Exon: Exons are streches of DNA inside the gene that do NOT get translated into protein.
