“Biologists have long attempted by chemical means to induce in higher organisms predictable and specific changes which thereafter could be transmitted in series as hereditary characters. Among microorganisms the most striking example of inheritable and specific alterations in cell structure and function that can be experimentally induced and are reproducible under well defined and adequately controlled conditions is the transformation of specific types of Pneumococcus.” WellsMeanLongCharacterConditionsExampleTypeHigherFunctionTransformationStructureSeriesDefinedCellsControlledChemicalsOrganismsPredictableGeneticsBiologistAlterationsHereditaryMicroorganismsStructure And Function Author:Oswald Avery
