Satellite DNA is a type of tandem repeat. The repeats sit next to each other, in tandem. These are multiple copies of the same base-pair sequence lying end-to-end.[1][2][3] Tandem repeats also include minisatellite and microsatellite DNA. Satellite DNA is the main component of centromeres. It forms the main part of heterochromatin.[4][5]
The most common type of tandem repeat is the heterochromatin, which sits on chromosomes around the centromeres and elsewhere. It is "transcriptionally inactive", meaning, it does not code for proteins.[6][7][8]
