Finding Ways To Keep Up With Fingerprinting

What are the Different Types of Fingerprinting Processes?

It is really hard to identify or authenticate a person until the discovery of fingerprints in 1984 and since then on, it has been developed and widely accepted all over the world as a way to authenticate a person’s identity. Fingerprints are the only thing that is found to be really unique from one person to another, hence the discovery of such has been used widely for identification purposes.

The first thing that will usually happen is that the person’s fingerprint will be taken by paper and as soon as it has been printed out, it will then be uploaded to the internet to be used for identification in the future but one downside to this type of technology is that people who have medical problems that does not allow them to give out a fingerprint sample, then it will be useless in the end.

Because such fingerprints are found to be not applicable for people who have specific health or medical problems, studies and developments were made to ensure that everyone will have their very own unique identification and this lapse led to the discovery of DNA, or deoxyribonucleic acid, a really unique composition only addressed to match only one subject. Since the discovery of DNA fingerprinting process, there have been so many instances that lead to bigger progresses and developments.

The discovery of fingerprinting processes did not end there and instead, continued to even further towards the boundaries, which led to having four types of DNA fingerprinting processes that we use today. To name, these various processes involve the restriction fragment length polymorphism or known as the RFLP, short tandem repeat or STR method, polymerase chain reaction or PCR and amplified fragment length polymorphism or AmpFLP.

A Simple Plan For Researching OptionsOf all these four types of fingerprinting processes, the STR or the short tandem repeat is considered to be the most common type and this is used mostly today but short sequential repeat DNA is also mixed to pull up and identify a specific person.

A Simple Plan For Investigating OptionsThe next type of fingerprinting process is the polymerase chain reaction process and what it does is it will take a smaller sample of the DNA in order to even magnify further to create exact replicas of the DNA itself but this type of process though, is not capable of providing or showing the exact results of the restriction fragment length polymorphism. The restriction fragment polymorphism will take the DNA fingerprinting results after it is analyzed with a radioactive probe.

Last but not the least, AmpFLP is very popular in smaller countries from around the world and they are popular in a way that it is less complicated that the rest and is also very much straight forward when compared to the other three but due to its less complicated feature, this has been pointed out to likely be the cause of misidentifications in some processes.
