1) the process of completing a DNA test is not very difficult.

2)collecte cells from a person's cheek using a swab.

The next step is to send this cell sample to a laboratory

extract the DNA from the swab

create many samples from it

the samples are put into a gel mixture

subjected to an electric current

A DNA probe can then be used, which attaches itself to the sample

analayze probe location

scientists develop the film of this unique DNA strand

3)First of all, Ultimately

4)now available on the Internet, and ordinary people can now order in-home DNA tests and get their results in just a few days.
