It's a way to amplify a specific strand of DNA. They split a DNA strand into two RNA strands. Use the polymerase enzyme to build one of the RNA strands back into DNA. Rinse, repeat.
Lol, how though, what is the process. You don't even know what temperature they have to heat the polymerase for it to develop polymer chains. You realize PCR is actually a derivative of the petrochemical industry from a process used to create plastic, and synthetic esters.
Polymer chains? What are you talking about. Polymerase is an enzyme. It's a molecular machine that does stuff, in this case attaches complementary base pairs to RNA to form DNA.
You have to be some midwit redditor because all you do is regurgitate google and wikipedia, and poorly at that. Here since you need to regurgitate authority because you're a spineless cunt.
This is the enzyme that's used in PCR
https://en.wikipedia.org/wiki/Taq_polymerase
Taq reaches its optimal polymerization rate of about 150 nucleotides per second per enzyme molecule, and any deviations from the optimal temperature range inhibit the extension rate of the enzyme.
If you don't understand what this means because mommy dropped you several times on your head while feeding you paint chips, the enzyme is heated and it polymerizes, like a burger on the grill that's allowed to cool to room temperature.
https://en.wikipedia.org/wiki/Polymer
A polymer (/ˈpɒlɪmər/;[4][5] Greek poly-, "many" + -mer, "part") is a substance or material consisting of very large molecules, or macromolecules, composed of many repeating subunits.
Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compounds, produces unique physical properties including toughness, high elasticity, viscoelasticity, and a tendency to form amorphous and semicrystalline structures rather than crystals.
Again, PCR test is like heating a burger in a grill and letting the oil cool into that waxy mess, the meat fat has polymerized.
