A 10-Point Plan for (Without Being Overwhelmed)

All about DNA Testing Works

Numerous people have already given DNA testing to be able to know more about their ancestry. Because of this, testing kits are a lot more popular today than they were before. In reality, there are more people who’ve used consumer DNA tests than the reports gathered in the years before 2018. Due to the reason that there are increasing number of people believed to use it, it’s projected to boom at around 100 million years just in the next two years.

Without a doubt, the hype is there but the question most people are wondering is how DNA testing works.

It is hard to give a simple answer to this question given the fact that every company has their own kit that uses proprietary algorithms in handling DNA data. On the other hand, if you are interested to give DNA testing a try, then here are few of the things that you need to be mindful about. First of all, DNA tests can be used in uncovering secrets or even discovering things that’s new even to you.

Where a person roughly came from, how closely you’re related to other members who are in the database and if you have specific traits are only few of the things that DNA tests can reveal. However, what you are going to get depends on what you’ve ordered but one thing’s for sure, you will learn whether you’re half of something and the other.

The DNAs basic building blocks are the person’s spit and the provider’s code. As for the spit, it’s pretty self-explanatory. What you have to do is to spit into a tube and send it to the provider and after receiving it, it’s their responsibility to extract DNA from the sample and have it digitized so by that, it can be stored in the database and make a profile.

And right after it is digitized, the DNA will look like a string of 4 nucleobases of DNA which includes C, G, T and A. This is where the proprietary algorithm of the provider will kick in to carry out DNA testing and it is where things are more complex.

Algorithms used here are so advanced and complex that it can pull out C’s, G’s, T’s, and A’s. By finding patterns, they can then derive the meaning. Then afterwards, everything here will remain a secret as each companies have their own pattern-spotting algorithm. However, there are roughly 600,000 positions to which human DNA codes differ and these are also known as single-nucleotide polymorphisms.

By the time when the DNA testing is done, it is forwarded to the DNA library where it is joined by other DNAs and from this point, it can tell you where your DNA came from.
