Just a quick link to an article this time – the 2007 Nobel Prize for Physiology/Medicine has been awarded to the scientists who developed the technique of gene targeting. This has allowed scientists to 'knock out' single genes, & by doing this to work out their function. My favourite science blogger, Orac, has just posted an excellent short article around this here, including a great explanation of how the technique works. Well worth reading for an outline of a new & significant technique in molecular biology.
