DNA storage is an important aspect of DNA extraction projects as it ensures the integrity and stability of the extracted DNA for downstream applications. [ 15 ] One common method of DNA storage is ethanol precipitation, which involves adding ethanol and a salt, such as sodium chloride or potassium acetate, to the extracted DNA to precipitate it ...
However, mummified remains are a limited resource. The majority of human aDNA studies have focused on extracting DNA from two sources much more common in the archaeological record: bones and teeth. The bone that is most often used for DNA extraction is the petrous ear bone, since its dense structure provides good conditions for DNA preservation ...
The general process for extracting DNA using the silica-based method is outlined by the following: [21] Bone specimen is cleaned and the outer layer is scraped off; Sample is collected from preferably compact section; Sample is ground to fine powder and added to an extraction solution to release DNA

DNA extraction from fossils is one of the more popular practices and there are different steps that can be taken to get the desired sample. [4] DNA extracted from amber-entombed fossils can be taken from small samples and mixed with different substances, centrifuged, incubated, and centrifuged again. [46]
This involved the analysis of nine skeletons, including those of the putative Tsarina and three of her daughters, and comparing their DNA to that of living descendants. [13] She has also used mitochondrial DNA to study the migration of human populations. [10] She has also extracted DNA from mammoth bones. [14]
Riverside, California, cold case homicide investigators used DNA technology to link a man who passed a lie detector in connection to a 1979 murder, to the crime.
