Abstract

DNA profiling, commonly called DNA fingerprinting or DNA testing, has a wide range of uses, including assisting in criminal cases and wildlife conservation. The firm tissues of the teeth are resistant to external events such as decomposition, bruise, and incineration. Pulp tissue provides a rich DNA source. The review focuses on the various DNA Collection Procedures, the different techniques employed in DNA isolation and amplification. There are a numerous DNA Profiling or Typing systems such as Mitochondrial DNA (mtDNA) analysis, Restriction Fragment Length Polymorphism, Y chromosome analysis, Single Nucleotide Polymorphism (SNP) typing , Short Tandem Repeat (STR) typing, Gender typing, X-chromosome STR Typing. DNA fingerprinting has been applied to solve many cases. Although present DNA analysis techniques are fairly specialized, several upcoming simplifications may increase their simplicity of use.
