The Induction of Mutations by Antibodies

In most biological syntheses each step is controlled by a different gene. This conclusion was suggested by such combined genetic and biochemical studies as those on the anthocyanin pigments from which it appeared that a particular gene regulates the oxidation (or methylation, or the nature of the glucosides) at particular carbon atoms of the anthocyanin molecules. Studies of the eye pigments of Drosophila and the hair pigments of guinea pigs each indicate that the different steps in a particular synthesis are controlled by different genes. Almost overwhelming support for the conclusion is coming from studies of "biochemical" mutations in Neurospora
