Abstract:
Human and nonhuman hairs are often recovered during forensic investigation. As with all other biological samples that may be collected, via DNA analysis, hairs have the potential to provide the investigating authority with valuable intelligence pertaining to the identity of offenders, victims and even pets. DNA analysis of hairs is not however a straightforward process. The biochemical make up of hairs provide the DNA analyst with a unique set of challenges that must be overcome before any useful information can be gleaned from the evidence. This short review provides an overview of the location and condition of DNA within hair samples, and discusses the analytical methods that are employed to maximise the information that can be obtained from this sample type.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
