Pcr dna sequencing

Pcr is the process  in which. You take any sample of Dna and you take it through these process where you put the Dna sample that you have and places it in a vile. The first step is Pcr amplifications. You add polymers and primers to make many pieces of your desired pieces of Dna. Then by heating and cooling these together in a PTC Machine.  you start making copies of that Dna. With the Polymers and primers that we added. The second step is purification. you put the tubes in a centrifuge to get all the dna separate from the rest. Then the third step is to dilute the product increase volume. Then start process over again. Tell you have as much Dna as you need. IF it is a diesed cell you were looking to find or your babies daddy. You would now have many copies of that cell that you can study if you want to find what the genetic codes to that specific cell. Then you will be able to find what ever you need  to know about that Dna Cell.
