Work

Organisms' metabolism - the chemical processes within its cells - are regulated by substances called enzymes. George Beadle and Edward Tatum proved in 1941 that our genetic code, our genes, govern the formation of enzymes. They exposed a type of mold to x-rays, causing mutations, or changes in its genes. They later succeeded in proving that this led to definite changes in enzyme formation. The conclusion was that each enzyme corresponds to a particular gene.
