The primary function of acetylcholine is to carry signals from motor neurons to the body's skeletal muscles.

Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology to exponentially amplify a specific DNA sample from a small amount of DNA. For this purpose, the PCR technique uses: 1- a DNA polymerase enzyme in order to synthesize new DNA copies and 2- one pair of DNA oligonucleotides (primers) which are complementary to the ends of the target DNA sequence. During each round of PCR, the double-stranded DNA template is unwound and each strand is used to synthesize a new DNA strand, thereby forming two new double-stranded DNA molecules. In consequence, each round of PCR doubles the amount of DNA.
