TRANSDUCTION: the trannsfer of a poion of the DNA from one bacterium to another by a abactriophage is known as transduction. Bacteriophages are viruses that parasitise the bacteria and consist of a nucleic acid core and a protein coat. a phage paicle may have its core beside its own nucleic acid a segment of hostDNA. When this paicle infects another bacterium DNA transfer is effected and the recepient cells acquire new characteristic coded by the donor DNA REF:Ananthanarayan and Panicker's Textbook ofMicrobiology 8thEdition pg no:63
