Picture under Procedure I m talking about the picture where the denaturation annealing and extension phases are shown I know there used to be another picture here like the one in the spanish pages that did not look as fancy The current picture does not show any PCR products because these are not made until the third cycle I suggest using the older picture that is also in the spanish section or make a new one that actually shows the first 3 cycles of a PCR and thus some PCR products Solveig
