This website is an interactive puzzle that allows you to use the clues that the Scientists involved in solving the structure of DNA, how DNA replicates and produces proteins. It has excellent animations.

A proper Scientific video (NB this has heaps of info - don't learn the deets, just let the amazingness of what the awesome enzymes are doing wash over you!)
A less proper but definitely more fun video on DNA replication.
WHO PROVED THIS? Meselson and Stahl
