Microsatellites, or Simple Sequence Repeats (SSRs), are polymorphic loci present in nuclear DNA and organellar DNA that consist of repeating units of 1-4 base pairs in length.
Microsatellite
Microsatellite are short tandem repeat (STR). The repeated units of sequences are usually between 2 and 7 base pairs. See also PCR Glossary.

This article is about the DNA sequence. See miniaturized satellites for orbiting artificial satellites with a mass of less than 100Kg.
Microsatellite
Microsatellite sequences are repetitive DNA sequences usually several base pairs in length. Microsatellite sequences are composed of non-coding DNA and are not parts of genes.
Microsatellite A DNA sequence of from 2 to 6 nucleotides which are tandemly repeated from about 5 to 5,000 times (usual range 20 - 50 repeats). A locus containing a microsatellite is often polymorphic because of variation in the repeat number.
Microsatellite
Highly polymorphic DNA marker comprised of mononucleotides, dinucleotides, trinucleotides or tetra-nucleotides that are repeated in tandem arrays and distributed throughout the genome.
Microsatellite: A microsatellite is a simple sequence repeat (SSR). It might be a homopolymer ('...TTTTTTT...'), a dinucleotide repeat ('....CACACACACACACA.....'), trinucleotide repeat ('....AGTAGTAGTAGTAGT...') etc. Due to polymerase slip (a.k.a.

How do I find microsatellite polymorphisms?
Answer: Direct retrieval of polymorphism data is not possible, but this data can be found by retrieving loci that are polymorphic.
The level of expression of the V1a receptor gene is controlled by a "microsatellite" region upstream (5') of the ORF. This region contains from 178 to 190 copies of a repeated tetranucleotide (e.g., CAGA).
So when you talk about RFLPs and microsatellites and this and that, they're all just different ways of [describing] DNA spelling differences. DNA polymorphisms let us track the inheritance of chromosomes in families and in whole populations.
Haplotype analysis of 192 Caucasian chromosomes revealed strong linkage disequilibrium between CCR5 and two microsatellite loci.
