If a patient sample contains 8 copies of viral DNA, predict how many DNA copies would be present following three rounds of PCR amplification
a. 16
b. 24
c. 32
d. 64
D
In amplification PCR–based testing, each cycle in the reaction doubles the amount of nucleic ac-id present and each new copy serves as a template for the next round, yielding an exponential amplification in copy number (2n).
