<prompt> Transfer of DNA from one bacterium to other by a bacteriophage is known asFormationConjugationTransductionTranscription  <response>: Ans. c Transduction. Ref. Textbook of Microbiology by Anantanarayan, 6th53TRANSMISSION OF GENETIC MATERIAL IN BACTERIA IS BY: Transformation:- Transfer of genetic information through agency of free DNA. Transduction:- Transfer of a portion of DNA from one bacteria to another by transduction phase.- It is not confined to transfer of chromosomal DNA.- It transduces epizomes plasmids also.- Bphages are viruses that parasitise bacteria consist of nucleic acid core a protein coat.- It is excellent tool for gene mapping of bacteria. Lysogenic conversion:- Phage DNA becomes integrated with bacterial chromosome as prophage, which multiplies synchronously with host DNA is transferred to daughter cells. This is lysogeny bacteria harbouring prophages are lysogenic bacteria.- In transduction phage acts as vehicle carrying bacteria genes from one cell to another but in lysogenic conversion phage DNA itself is new genetic element. Conjugation:- Process where by male or donor bacterial mates or makes physical contact with female or recipient bacteria transfer genetic element into it. Sexduction:- Process of transfer of host genes through F factor resembles transduction known as sexduction.
