Extraction of DNA from Shark Teeth and Denticles
Extraction of high-quality genomic DNA from the dermal denticles and fragment of tooth enamel of a shark has enabled identification of a specific shark. The study describes a non-invasive process that allows collection of genetic samples from a shark. It details the procedure utilizing PCR analysis of a shortfin mako shark, Isurus oxyrinchus, that permitted isolation of genomic DNA of satisfactory size and quality to identify an individual shark.
