Area of Science:

  • Genomics
  • Molecular Biology
  • Human Genetics

Background:

  • Microsatellites are abundant repetitive DNA sequences in the human genome.
  • Their characteristics include ubiquity, PCR typability, Mendelian co-dominant inheritance, and high polymorphism.
  • These features make them valuable genomic markers.

Purpose of the Study:

  • To highlight the diverse applications of microsatellites in genetics and biology.
  • To explore the role of microsatellites in human disease aetiopathogenesis.
  • To discuss the insights microsatellites provide into fundamental biological processes.

Main Methods:

  • Review of existing literature on microsatellite DNA.
  • Analysis of microsatellite applications in various fields.
