We use genetic screening to establish the genes which are responsible for the production of specific proteins. When this technique was developed it was heralded as the ultimate solution: 'the answer to life, the universe and all that'; but as time has gone on we have come to recognise that it is extremely rare to be able to link one particular gene to the production of one particular protein because the expression of proteins involves the influence of many genes.
