Forensic Science – DNA Evidence

With increasing sensitivity of DNA profiling methods, we can now obtain reliable DNA profiles from just a few cells. We no longer need a detectable body fluid, such as blood or semen, to give a good quality DNA profile. Instead, so-called ‘trace DNA’ can be recovered for which the biological source is unknown, be it a body fluid or indeed any other tissue, such as skin. This makes it increasingly difficult to assess whether the DNA recovered really came from someone involved in the crime.
