WebA fluorophore is excited most efficiently by light of a particular wavelength. This wavelength is the excitation maximum for the fluorophore. Light with a wavelength near the excitation maximum can also cause excitation, as shown by the shaded areas below, but it does so less efficiently. Excitation range and maximum. WebSimilar to DNA replication that occurs under normal biological conditions, the PCR requires a DNA polymerase to make the new strands of DNA. The polymerase that is used in the PCR reaction is called “ taq polymerase”, as it was originally isolated from the heat-tolerant bacterium T hermus aq uaticus that normally live in hot springs and ...
