microsatellite

in genetics
synonym: short tandem repeat (STR)
https://doi.org/10.1351/goldbook.10963
Non-coding segment of DNA consisting of short nucleotide sequences (\(\pu{2\!{-}\! 6}\) base pairs), typically occurring in \(\pu{10\!{-}\! 100}\) consecutive (tandem) repeats.
Notes:
  1. The number of repeats varies between members of any given species.
  2. Microsatellites are used as markers in determining genetic diversity, in identifying important genetic traits, in forensic science, in population studies, and in determining paternity.
