原始语种摘要: Abstract(#br)Thermal degeneration of the DNA molecule presents a special challenge to medico-legal investigations since low DNA yields, fragmented DNA molecules, and damaged nucleotide bases hinder accurate STR genotyping. As a consequence, fragments of severely burned human remains are often not amenable to standard DNA recovery. However, current ancient DNA (aDNA) extraction methods have proven highly effective at obtaining ultrashort DNA fragments (∼50 bp) from degraded palaeontological and archaeological specimens. In this study, we compare DNA yields and STR results obtained from two established aDNA and forensic DNA extraction protocols by sampling multiple skeletal elements recovered from victims (n = 23) involved in fire-related incidents. DNA yields and STR results suggest an...
