What occurs during the exponential phase of classical PCR?

Explanation:
During the exponential phase, the amount of DNA doubles each cycle, so the product accumulates rapidly. When fluorescence is used to monitor the reaction, the signal rises as more double-stranded DNA is present. Because the quantity of amplified product at a given cycle is proportional to the starting amount of template (more starting copies yield more product), the fluorescence increase mirrors the starting template quantity. This is why the statement that fluorescence increases proportionally to the starting template best describes what happens in this phase.
