Francis Crick proposed the Central dogma in molecular biology,
He concluded that the $R$ strain bacteria had somehow been transformed by the heat-killed $S$ strain bacteria. Some ‘transforming principle’, transferred from the heat-killed $S$ strain, had enabled the $R$ strain to synthesise a smooth polysaccharide coat and become virulent
