1962 Amer. Jrnl. Bot. 49 943 In the second satellite chromosome pair she [sc. Cauderon] found a microsatellite.
1984 Silvae Genetica 33 56 Previous studies show that Sequoia has 6 nucleoli, 4 large and 2 small, which indicates that there are 2 other active NOR present, likely associated with microsatellites which may not be visible due to pretreatment effects.
1989 Bot. Gaz. 150 465/2 A terminal secondary constriction (observed as a microsatellite on the short arm) was found in pair 5.
1995 Amer. Jrnl. Bot. 82 277/2 Most of the satellites attached to NOR-carrying chromosomes display variation in size... In general, they appear as microsatellites..or macrosatellites.
b. A short segment of highly repetitive DNA in which the repeated unit consists of two or four nucleotides. Frequently attributive. Cf. satellite n. 10, minisatellite n.

1989 Amer. Jrnl. Human Genetics 44 397 Since minisatellite regions with larger repeat elements often display extensive length polymorphisms, we suspected that (TG)n repeats (‘microsatellites’) might also be polymorphic.
1994 Dog World Feb. 5/1 (advt.) Stormont Laboratories introduces the latest in DNA microsatellite technology.
1997 N.Y. Times 14 May b. 9/3 They crushed young grapevine leaves from each of the varieties, extracted DNA from the leaves and examined 30 distinct DNA sites, known as microsatellite markers.
1998 Nature 15 Oct. 637/1 Microsatellites are repeats of short DNA segments, widely distributed in our genome, that are commonly used in evolutionary analyses because they are numerous, inherited in Mendelian fashion, highly variable and easy to handle.
2. Astronautics. A very small planetary satellite (rare); a very small man-made space satellite.

1962 Science 2 Mar. 720/1 Cosmic dust, micrometeorites, meteorites, cometary nuclei, microsatellites (of Mars, Jupiter, Saturn), and asteroids are all vestiges and products of the breakup of the terrestrial planet postulated by Olbers to account for the minor planets.
1991 Science 23 Aug. 848/1 Its latest satellite, called UoSat-5, is the size and weight of a backpack. Sweeting is the pioneer of the ‘microsatellite’.
1993 Independent on Sunday 17 Oct. (Business section) 6/4 There have been some limited applications [for aerogels], such as..catching microsatellites—which burn up going through the atmosphere—by fixing aerogel tiles on the outside of spacecraft.
1995 Daily Tel. 1 Nov. 20/5 Satellites as small as a box of cornflakes can be launched at little cost by riding piggyback with larger satellites. A handful of these ‘microsatellites’ would be used instead of a single all-singing all-dancing ‘platform’ bristling with instruments.
1999 U.S. News & World Rep. 8 Nov. 33/1 (caption) Instead of large reconnaissance satellites, spy agencies hope to operate clusters of less expensive microsatellites that would allow broader coverage of Earth.
