Draw a figure, create a concept map, or construct a table that distinguishes conjugation, transformation, and transduction … Bacterial Transduction - Generalized and Specialized Transduction: The virus mediated gene transfer in bacteria. Transformation is the uptake of genetic material from the environment by bacterial cells. GENE TRANSFER IN The key difference between transformation and transduction is that transformation is a mechanism which alters the genetic material of bacteria by direct uptake of exogenous genetic material from its surroundings through the cell membrane and incorporation of it into the genome while transduction is the injection of foreign DNA by a bacteriophage virus into the host bacterium. This method was proposed by Lederberg and Tatum. Transduction, transformation, conjugation, transposable elements. Chapter 13: pp. Recombination in bacteria By. • It is the incorporation of exogenous genetic material from its surroundings through the cell membrane (s).
