Molecular Genetics is the study of molecules and mechanisms involved in genetic inheritance. The molecular understanding of DNA has resulted in an explosion of research and in the creation of a new field called Genomics
Fragment analysis:
The species-specific microsatellite DNA sequences consist of tandemly repeated nucleotide motifs occurring throughout the genomes of eukaryotes. Microsatellites currently are the markers of choice for the molecular characterization of livestock genetic resources. The number of repeat units at a microsatellite locus may differ, so alleles of many different lengths are possible. Microsatellite loci are used as molecular markers to establish:
- Individual identification
- Parentage verification
- Population and Linkage analysis
- Investigation of forensic cases
Sequencing:
DNA sequencing is the determination of the precise sequence of nucleotides in a sample of DNA using the dideoxy method or Sanger method. This is the gold standard for sequencing and a confirmatory tool for:
