This week we take a foray into forensics, as DI Alan Cook talks about how DNA is used to solve crime, Alec Jeffreys helps us brush up on how DNA fingerprinting works, Tamsin OConnell describes how DNA can help track down human origins, and in Kitchen Science we have a live DNA fingerprinting race in which schools battle it out to discover which of the Naked Scientists is the foul footed felon with the criminally smelly feet.
