The Necessity Of DNA Confidentiality
The Necessity Of DNA Confidentiality The DNA of every individual is unique. Even identical twins have variations in their DNA that makes it unique. DNA can not only be used to identify a person but can also reveal medical issues and project potential health problems that may arise in the future (DNA test company 23andMe…

The Role Of DNA In Forensic Science
The Role Of DNA In Forensic Science The origin of DNA fingerprinting was discovered in 1984 by Dr Alec Jeffreys (Jackson and Jackson, 2011, p. 158). Over the decades, with technical developments in genetics, the original DNA fingerprinting procedure has undertaken a variety of modifications and refinements. DNA profiling has become so precise and sensitive…
