simple repeated sequence

Microsatellite is the tandemly repeated fragment in genomic sequences, composed of 1-6 base pairs in length, so microsatellite also called Short Tandem Repeat ( SIR) or Simple Repeat Sequence ( SSR).

微卫星（Microsatellite）是基因组上由1-6个核苷酸为单位组成的重复，又称串联重复序列（Short Tandem Repeat，STR）和简单重复序列（Simple Sequence Repeat，SSR）。

Microsatellites or SSR ( Simple Sequence Repeats) are short ( 1~ 6 bp), tandemly repeated DNA sequences.

是指以1～6个串联核苷酸为单位的重复DNA序列。
