INTRODUCTION All eukaryotic genomes contain regions of simple repetitive DNA, called short tandem repeats (STR*) or microsatellites, which consist of tandem repeats of a small number of bases (1-3). The number of repeats at a STR locus can be highly variable among individuals, resulting in length polymorphisms that can be detected by relatively simple PCR-based assays. Thousands of these highly...

this study was designed to find out the impact of the variable number of tandem repeats (vntr) of the tumor necrosis factor receptor 2 (tnfrsf1b) on pulmonary tuberculosis (ptb) risk in an iranian population. this case-control study was done on 159 ptb patients and 158 healthy subjects. bi-allelic tnfrsf1b vntr was genotyped by polymerase chain reaction. logistic regression analysis revealed no...

Microsatellites or simple sequence repeats (SSRs) are very effective molecular markers in population genetics, genome mapping, taxonomic study and other large-scale studies. Variation in number of tandem repeats within microsatellite refers to simple sequence length polymorphism (SSLP); but there are a few studies that are showed SSRs replication slippage may be occurred during in vitro amplifi...

In this paper, we use Kolmogorov complexity and compression algorithms to study DOS-DNA (DOS: de-ned ordered sequence). This approach gives quantitative and qualitative explanations of the regularities of apparently regular regions. We present the problem of the coding of approximate multiple tandem repeats in order to obtain compression. Then we describe an algorithm that allows to nd eecientl...
