Abstract: | DNA extraction from bone is an important issue particularly in paternity cases when bones are the only remaining material to obtain and analyze DNA. The difficulties arising from bacterial damages, taphonomic factors and diagenesis might negatively affect the extraction and the amplification of DNA. This makes the laboratory procedure a hard and time-consuming process, and the analysis can fail. Analyzing mini-STRs in this type of degraded samples is highly recommended. In this study a new extraction technique was carried on bone samples which were then typed for mini-STRs. The aim was to differentiate two genetically related skeletons found in the same familial grave for a paternity test. The analysis revealed that this new extraction technique along with mini-STR analysis can properly be an effective way to obtain and analyze DNA in bones in the field of forensic sciences. |
