The year is 2023 and someone has robbed a casino in Las Vegas, and DNA has been recovered. Students are provided with a sequence from the DNA and a key telling which amino acids code for which physical characteristics. They decode the DNA into mRNA, then into amino acids, and then into physical characteristics. Finally, they draw a sketch. This is a lot of fun, but I'm afraid it gives the impression that genes map more directly to phenotypes than they actually do (as with the God gene, the Alzheimers gene, etc). What do others think? Can that be minimized?
