Also, some helpful videos on DNA Replication and Protein Synthesis

These videos are a little longer (~14 min) than most, but the material is a little more digestible and easier to follow. It's not as good as Prof. B's DNA rap video, but I've found both of them to be quite helpful. There may be some terms you don't understand, but don't worry too much about them. Enjoy!
