Human beings have always had a curious mind. We want to know things that are beyond our approach. We want to learn the mysteries of the world and justify the phenomenon going around in the universe. One of the most intriguing objects of study is the human being itself. DNA testing is one of the ways to know the human body.
DNA testing is possible today because of scientific advancements. A person can get gas DNA tested for various reasons from reliable places like CRI Genetics and understand his complex body.
Here is what you need to know about DNA testing.
What Is DNA Testing?
DNA testing is an analysis of human DNA at the deepest level. DNA contains all the necessary information required to build a living body. This necessary information is stored in the form of chromosomes. DNA testing allows scientists to see the sequencing of the chromosomes and understand the uniqueness of an individual.
DNA testing is a medical test that can help scientists identify changes in the genes, the production of proteins, and identify any genetic condition that a person might be exposed to.
How Is DNA Testing Carried Out?
If a person needs to be analyzed genetically, the healthcare provider will arrange DNA testing for the patient. Now as the technology has advanced, you can buy a DNA testing kit and deposit your sample to a laboratory to run the tests.
DNA testing is done in four steps.
1. Extraction
The DNA sample is extracted from the source. The source can be the human body; hair samples, body fluids, skin or fingerprints from a crime scene, DNA samples from the victim’s body, etc. The aim is to get the DNA sample that needs to be tested.
2. Quantitation
In this step, the quantity of the sample DNA is determined and amplified to make multiple copies. Amplification is important to run the test accurately.
3. Separation
The amplified DNA is then separated and prepared for the test. The test is done by keeping in mind the purpose behind the test, whether the client wants linkage, is there any abnormal sequencing that needs to be determined, or under/overproduction of a certain protein.
4. Analysis
The results of the test are then analyzed and compared to the normal DNA sequencing. Comparative analysis allows technicians to identify any abnormal behavior in the results.
What Does A DNA Test Tell You?
Coming towards the benefits of DNA testing, the list is long. DNA testing is of great use in a person’s life. Here is what you can get from DNA testing.
1. Ancestry
A DNA test can help you find your ancestors. If you have always been curious about how you got blue eyes while none of your parents or grandparents have blue eyes, or you are curious to know where you came from, DNA testing can help you answer many of these questions. Some DNA tests can link you back up to 50 generations. You can find your lineage this way.
2. Health Analysis
DNA tests can be used to find out your health conditions. If you or your future generation is exposed to any genetic condition, if you are prone to cancer, or not. Such questions can help reduce the cases of genetic mutilation in future generations. You can also find out how your body absorbs nutrition, and what you can do to maintain your weight.
3. Forensic Uses
DNA testing can be a great tool to identify murderers, rapists, and other criminals with greater accuracy. Forensic scientists can match the accused sample with the culprit’s sample and give a face to the DNA samples collected from the crime scene.
