Mr Eardley gave the youngest WP members an A-level Biology lesson, which involved looking at the detailed structure of DNA, using knowledge of the structure to explain exactly what is meant by “the genetic code”, explaining how cells read the genetic code and follow the instructions it gives to make proteins, and, finally, considering what happens when things go wrong – the code is misread or the amount of DNA is changed – and mutations are produced. Clear, challenging and fascinating.
