= DNA Sample Extraction Methods =

==== Extracting DNA from a sample can be performed through a variety of methods. Contamination to samples can reduce the quality of the DNA being analyzed, so it is very important to follow the appropriate protocols. Extraction methods include, but are not limited to, phenol-chloroform extraction, Ion-exchange-based methods using Chelex resin, silica-based extraction, and the most recent prominent method is the DNA purification using magnetic beads (Zietkiewicz et al., 2012). Speller et al. (2012) identified the remains of a 2.41g portion of a skull, a first upper molar, and an upper first premolar using a silica spin column extraction method. Each extraction method has their own advantages and disadvantages, and methods are chosen based on the type of sample present. ====
