Major features of the most represented tandem repeats in the human genome.
Repeat type | Unit length | Array length | Estimated % genome coverage | ||
---|---|---|---|---|---|
Tandem | Satellite | Alpha-Satellite | 171 bp | 3–5 Mb | 22–25% |
Satellite II (HsatII) | 23–26 bp or multiple | 10–70 kb | |||
Satellite III (GAATGn- simple sequence) | 5 bp or multiples up to 70 bp | 7.5–100 kb | |||
Beta-Satellite | 68 bp | 2–14.5 kb | |||
Gamma-Satellite | 220 bp | 10–200 kb | |||
VNTR (Variable number of tandem repeats) | Microsatellite (Short tandem repeat) | 1–13 bp | Hundreds bp | ||
Minisatellite (including telomeric repeats) | 6–100 bp | 1–15 kb or more | |||
Macrosatellite | 2–12 kb or more | Tens up to hundreds bp |
Genome coverage is estimated on the basis of current genome coverage.
