Sometimes, bones are the only accessible source of DNA, thanks to their structure, which preserves DNA comparatively well and for a long time. The main problems of DNA extraction from bones are DNA degradation due to environmental factors and the presence of soil-derived inhibitors like humus acids [1â10].
Such damage to the bone indicates differences may exist in quality and quantity of DNA extracted. This study assessed how five processing procedures used by major forensic anthropology laboratories around the country affects the amounts of DNA extracted from human rib bones and the subsequent DNA analysis.his study assessed how five processing procedures used by major forensic anthropology laboratories around the country affects the amounts of DNA extracted from human rib bones and the subsequent DNA analysis.
