The DNA Biotechnology Use in Forensic Science

Abstract

The study aims at understanding the role of DNA in biotechnology use in forensic sciences. Every organism has unique DNA sequences just like each individual has got unique finger print. In forensic science individuals are identified by scanning for 13 DNA regions, that vary from person to person and they use this information to create DNA profile or DNA fingerprint of that particular individual. There is very little possibility of another person having the same DNA profile or DNA fingerprint for this particular 13 DNA regions. At present identifying each individual belonging to same species is little bit less precise, but as the technology of DNA sequencing progresses, comparison of large part of genome or DNA fragment or even the whole genome will become feasible, easy and also precise in identifying individuals belonging to the same species.
