The association of a DNA or RNA strand to its complement is one of the basic research tools of the molecular biologist. Binding of a compliment can identify target regions of DNA or RNA, and can be used to disrupt the process of DNA manufacture. If the complementary DNA is labeled with a compound that fluoresces, then the binding of the fluorescent probe can actually be visualized using a microscope<span>. This permits the "real time" examination of </span>DNA synthesis.<span>
