DNA analysis of biological remains is useful to solve sets of problems related to forensic cases, identificaion of plants and infectious agents.

Determination of DNA of victims of conflicts and persecutions

A human body can be identified through the sequencing of its DNA and of the one of the relatives of the victim. The identification can help in the reconstruction of the facts and in the restitution of the body to the family (Szleszkowski et al. 2014). The DNA of a buried body is easily exposed to contaminations, for this reason, controls about DNA quality and the impact of contaminant agents can be necessary (von Wurmb-Schwark et al. 2008).

DNA analysis of ancient seeds

The effectiveness of DNA analysis of ancient seeds depends on the state of conservation of the sample that can be compromised by its cooking. The identification of the DNA of a seed permits to know the species that were cultivated in the past in a certain region and to determine their geographic diffusion (Fernández et al. 2013).

DNA analysis of bacteria, fungi and virus conserved in ancient human tissues and bones

Bacteria, fungi and virus in ancient human remains can be conserved in bones and tissues, especially in calcifications like dental calculus. The identification of the DNA of this agents is important to know their evolution during the time and can be useful to develop new methods too fight these infectious agents in the present times. The interest about the original infectious agents is growing up due to the developing of resistance to the antibiotics of the present ones (Preus et al. 2011).
