Introduction

• Tandemly repeated DNA sequences are widespread
  throughout the human genome.
• These tandemly repeated regions of DNA are
  typically classified into several groups
  depending on the size of the repeat region.
• Minisatellites (Variable Number of Tandem
  Repeats, VNTRs) have core repeats with 9- 80 bp
• Microsatellites (Short Tandem Repeats, STRs)
  contain 2-5 bp
• repeat varieties (dinucleotide repeatsCA,
  AT, TC, trinucleotide repeats TTA,
  tetranucleotides, pentnucleotides, etc.).
