 Mammalian-wide interspersed repeat

Mammalian-wide interspersed repeats (MIRs) are a class of genetic elements found in the genomes of mammals. They are a type of transposable element, specifically classified as short interspersed nuclear elements (SINEs). MIRs are thought to have originated from retrotransposition events and are characterized by their relatively short length, typically ranging from about 100 to 300 base pairs.
