The intergenic region is a region of DNA that is present between two successive genes in the chromosome. It can also be stated as a stretch of DNA sequences that are located between the adjacent genes. These regions are composed of noncoding DNA. They are thought to control certain genes but the majority of these regions do not have a proper function to perform.
Sometimes, these DNA sequences are also termed as junk DNA. Some functionally important elements for example promoters and enhancers along with noncoding RNAs are also present. These non-coding RNAs perform some regulatory functions in a cell.
