Polymerase chain reaction lesson

Hi, this is a powerpoint and accompanying worksheet about PCR. There is a video which can be found on you tube and some links to useful animations. I worked through it, set some exam-style questions and let them use the computers to have a go at the PCR simulation themselves on the last slide - or you can just do it on the whiteboard! Please rate it and let me know if you find it useful or have any suggestions for improvement! P.S. I think I have adapted this from another TES resource so again thanks for the original!
