Figure 4.- (A) Emission spectra (l ex = 480 nm; Dl ex = Dl em = 10 nm) of a solution of fluorescein-ss-cDNA upon addition of its complementary strand at 0, 2, 4, 6, 8, 10, 12 and
24 hours of reaction. (B) Emission spectra of the control solution of fluorescein-ss-cDNA,
recorded in the same experimental conditions than A.
