Transduction generalized and specialized transduction. In logic, statistical inference, and supervised learning, transduction or transductive inference is reasoning from observed, specific (training) cases to specific (test) cases. In contrast, induction is reasoning from observed training cases to general rules, which are then applied to the test cases. The distinction is most interesting in cases where the predictions of the transductive model, This chapter focuses on the mechanisms of genetic transduction in the Gram-negative bacteria. The major emphasis is on generalized transduction by a variety of bacteriophage, carrying both small.

Sep 02, 2014В В· Transduction; Transduction is the transfer of genetic information from a donor to a recipient by way of a bacteriophage. The phage coat protects the DNA in the environment so that transduction, unlike transformation, is not affected by nucleases in the environment. Not all phages can mediate transduction. Aug 27, 2013В В· 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.

Some phages are able to “mobilize” bacterial genes and carry them from one bacterial cell to another through the process of transduction. Thus, transduction joins the battery of modes of genetic transfer in bacteria—along with conjugation, infectious transfer of episomes, and transformation.
