Sequences with short repeating units
simple sequence repeat (SSR) are composed of short (1 to 5 bp), tandemly repeating units that are exact in identity and repetition. Although the elongation of SSR tracts may be due to more than one mechanism, much is thought to be the result of slip-strand replication errors. In the process of nascent strand formation, reannealing can occur. And when the strands contain repetitive elements, such as with SSR tracts, the annealing can be imperfect, leading to the addition of the same elements. The errors become permanent when an additional round of replication occurs before they are discovered by repair enzymes.

Some biochemists use the descriptor polymeric and modifications thereon in order to describe a repeat more precisely, e.g.:
homopolymer or heteropolymer
poly()
        dU/dY
        dU.dY
        dU:dY
        poly(dU).poly(dY)
    polypurine.polypyrimidine

The most abundant SSR tracts are the homopolymer repeats poly(dA).poly(dT) and poly(dG).poly(dC).
