I have no doubt that many of you did not understand the principle of PCR in the lecture; it is really hard to get it in 20 minutes. I hope that the printed material helped you a little bit better.
Moreover, many of those who understand the principle still cannot imagine how things are performed in practice.
It is very hard to get enough PCR thermocyclers to let you all perform the reaction, but you may enjoy the following links that present illustrations and animations on the principle and methodology of PCR and gel electrophoresis.
Now, more resources:
– PCR (The University of Alabama in Huntsville Laboratory for Structural Biology)
– Principle of the PCR
– PCR animation (The page takes a while to launch but it’s really worth waiting. BEST ANIMATION TO DELIVER THE AMPLIFICATION CONCEPT)
– Another good animation
Please suggest more links and I will put them one by one for you…
