Describe the relationship between Chemistry and PCR test

In Chemistry, proteins are defined as biomolecules that are essential for the human body to maintain homeostasis. In a PCR test, short for Polymerase Chain Reaction test, scientists are tracking for a certain chemical substance in our body that may be present in the process of protein synthesis or DNA replication that could possibly show if a person is positive for the Corona Virus.Therefor, the relation between Chemistry and the PCR test is that, without Chemistry, the PCR test would not be able to stand on its own, which in other words means the PCR test is dependent upon the presence of Chemistry.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
