The advantages of
DNA-based analysis are manifold: "rstly, due to the
ubiquity of DNA (all cell types of an individual contain
identical genetic information rendering analysis independent
of the origin of the sample e.g. blood, muscle, bone
etc.); secondly, the information content of DNA is higher
compared to proteins due to degeneracy of the genetic
code; thirdly, DNA is a rather stable molecule allowing
its extraction from many di!erent types of sample
