When scientists first observed this behavior it seemed that genes were transforming one type of bacteria into another so they concluded there must be a ‘transforming principle’ at work. Transformation occurs when one bacterium picks up free-floating DNA and incorporates it into its own genome. Griffith called this process transformation because one strain of bacteria (the harmless strain) had changed permanently into another (the disease-causing strain). Griffith concluded that the heat-killed bacteria passed their disease-causing ability to the harmless strain. Why did Griffith call it the transforming principle? What evidence suggested that there was a transforming principle? When the mice died and Griffith found live S bacteria in blood samples from the dead mice! Griffith concluded that some material must have been transferred from the heat-killed S bacteria to the live R bacteria. What evidence from Griffith’s investigation suggested that there was a transforming principle? In molecular biology and genetics transformation is the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material from its surroundings through the cell membrane(s). Term given to the substance that could be transferred from non living cells to living cells causing the living cell to show characteristics of the non living cell.
