The transducing phase with the bacterial chromosome now infects a second bacterium (recipient bacterium), and the donor DNA enters the cytoplasm of the second bacterium. This results in an infectious virus particle containing bacterial DNA, but one that can no longer replicate in the bacterium due to the loss of all of the phage DNA. Conjugation; Transduction; Transformation; Bacterial Conjugation. Conjugation is the technique of transfer of genetic material from one bacteria to another placed in contact. This method was proposed by Lederberg and Tatum. They discovered that the F-factor can move between E.coli cells and proposed the concept of conjugation. In transformation, a bacterium takes up a piece of DNA floating in its environment. In transduction, DNA is accidentally moved from one bacterium to another by a virus. In conjugation, DNA is transferred between bacteria through a tube between cells. Transposable elements are chunks of DNA that "jump" from one place to another. Conclusions Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell- to-cell contact or by a bridge-like connection between two cells; it is regarded as the bacterial equivalent of sexual reproduction or mating since it involves the exchange of genetic material. Bacterial Conjugation Definition Conjugation is the transfer of a plasmid or other self-transmissible DNA element and sometimes chromosomal DNA from a donor cell to a recipient cell via direct contact usually mediated by a conjugation pilus or sex pilus. Recipients of the DNA transferred by conjugation are called transconjugants. Conjugation [edit edit source] Bacterial conjugation is the temporary direct contact between two bacterial cells leading to an exchange of genetic material (DNA). This exchange is unidirectional, i.e. one bacterial cell is the donor of DNA and the other is the recipient. In this way, genes are transferred laterally amongst existing bacterial as opposed to vertical gene transfer in which genes are passed on to offspring. Transduction: In this type of sexual reproduction of bacteria, foreign genes are transferred into a bacterial cell with the help of a virus. These viruses are called bacteriophage and they are not virulent. The virus acts as a carrier vehicle and passes over genes from one host to another. Transducing bacteriophages may carry the same genes in which the reproduction method would be known as restricted transduction. They can also carry different genes at different times in which the ... CONJUGATION . Conjugation is thought to have evolved through transduction, and relates to the generation of defective viral DNA. This can be transcribed to produce singular viral elements, which cannot assemble or lyse the host cell. Such DNA strands are known as plasmids. They are circular and can either be integrated into the main chromosome, in which case they are replicated along with the chromosome and passed to daughter cells, or they are separate from it and can replicate ... It is also a process of genetic recombination in bacteria, where two cells conjugate and a segment of DNA transfers from one another. 2. Here two bacterial cells come in contact and a conjugation tube is formed. 3. In addition transformation is widely used in recombinant DNA technology. 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. In most cases gene transfer is between members of the same bacterial species. However, if a particular phage has a ...
