Current Application Of DNA Identity Testing

Techniques Involved In DNA Testing

D NA identity testing, which is also commonly known as DNA fingerprinting, is a test done to identify an individual's genetic traits on the basis of his genetic makeup. DNA identity testing was discovered in 1984 and has helped many people ever since. A DNA profile is a small and unique set of DNA which is different for all individuals. It's like a fingerprint that is unique for each and every individual hence the name DNA Fingerprinting. DNA fingerprinting finds its uses almost everywhere in today's time. Some of its biggest uses are:

and the other is a maternity test which tells whether a woman is the biological mother of a child. The test can also determine whether someone is the biological grandparent of the child. DNA testing is the most advanced and most widely used technique for parenting testing in today's times because of its ease and the accurate results it gives. The DNA testing of an unborn child is also possible which has been helpful in solving many family feuds where the father of the unborn child was not confirmed.

This is very useful for orphans who want to find out their family background. The test is also done to know what ancient community the person belongs to. The family tree can also be very helpful in determining any genetic disorders or diseases that a person may have now or in the future. This helps a person take precautions beforehand and has saved so many people from developing genetic diseases.

DNA Profile

The creation of the database is done for record keeping by the government and also non-governmental organizations. The police keep the records of the criminals and potential criminals in order to solve crimes. Schools and colleges might sometimes keep the genetic database of the students for information purposes. Laboratories maintain the database of the people to run various tests on them and to make new discoveries.

Identification Of Flora And Fauna

Botanists and zoologists are finding new species of organisms each and every day and classifying them into categories is very important. The DNA sample from these organisms is taken and then are tested and matched with existing ones. This has helped scientists to classify plants and animals with ease. In the older times, there were numerous techniques that had to be done to classify plants and animals and the results were never as accurate as DNA identity testing. This technique has helped scientists maintain a catalog of the various species.

Identity Testing is one of the best inventions in our times. It has made the lives of many people easier. It has helped solve numerous criminal cases and continues to do it till date.
