Cancer Treatment Research. However, current whole-genome amplification (WGA) methods are limited by low accuracy of copy-number variation (CNV) detection and low amplification fidelity. Template DNA and PCR. DNA polymerase (responsible for DNA replication) enzymes are only capable of adding nucleotides to the 3-end of an existing nucleic acid, requiring a primer be bound to the template before DNA polymerase can begin a complementary strand. As little as a single copy of a DNA segment or gene can be cloned into millions of copies, allowing detection using dyes and other visualization techniques. The RCA product is a concatemer containing tens to hundreds of tandem repeats that are complementary to the circular template. Amplification is required because a single piece of DNA is nearly impossible to work during molecular and genetic analyses.
