Decoding DNA: Forensic Genetics and the Evolution of Criminal Investigations
Author : Ekta Kumari, SEM VI, B. Sc - M. Sc Forensic Science (Integrated), National Forensic Sciences University, Gandhinagar DNA is the most potential and accurate source of identification and plays a crucial role in forensic investigations. A cell contains 2 types of DNA i.e.it can be either nuclear DNA (inherited from both the parents) or Mitochondrial DNA (inherited from mother only) and based on the quantity and source of evidence it is determined which DNA should be extracted for further analysis. Like for example, if hair is found on the crime scene as trace evidence, if the root part of hair is present then nuclear DNA can be evaluated and if only the shaft of hair is present then mitochondrial DNA should be evaluated. Sequence polymorphism plays a major role in analysis of DNA samples which can be achieved through the repetitive DNA sequences which can be either interspersed repetitive DNA sequences or tandem repeats. Interspersed repetitive DNA sequences can be present...
