DNA Fingerprinting

Technology has a vital role in the assessment and diagnosis of health problems. Fingerprinting technology is useful in health science research. Every Individual’s DNA has specific patterns and DNA fingerprinting is used to identify the patterns of DNA (Forensic Science, 2014). Personal identification can be tested and proved with DNA fingerprinting. Restricted fragment length polymorphism (RFLP), Polymerase Chain Reaction (PCR), Amplified fragment length polymorphism (AmpFLP) and short Tandem Repeat (STR) are main DNA fingerprinting methods (fingerprinting, 2014).  Hair, tissue and blood samples are used for DNA fingerprinting. Study cases, study questions and organisms are considered to select DNA finger printing technique (Chai, 2008).

DNA fingerprinting technology can be useful to find out the genetic traits of living beings and even dead bodies. According to Templeton (2013), DNA printing can be applied in synthetic biology to create a new life by substituting a genome. DNA printing is a quicker and less expensive method for gene therapy, working with viral genes and vaccine research (Templeton, 2013).

DNA printing has a wide range of applications including paternity disputes, identification of bodies of soldiers killed in war, diagnosis of inherited disorders like cystic fibrosis, sickle cell anaemia, thalassemia, haemophilia, Alzheimer’s disease, Huntington’s chorea and marfan’s syndrome (Medindia, 2014). DNA printing can be used in biological evidence to identify criminals and data storage of personal identifications (medindia, 2014). Cossins (2012) mentioned about a geneticist Craig Venter for his idea about a 3D DNA printer. The proposed 3D DNA printer can download, print and inject vaccines at home.
