Silene tatarica microsatellites are frequently located in repetitive DNA
Abstract The genomic distribution of microsatellites can be explained by DNA slippage, slippage like processes and base substitutions. Nevertheless, microsatellites are also frequently associated with repetitive DNA, raising the question of the relative contributions of these processes to microsatel...
