In Gram-negative bacteria it typically involves a conjugation or sex pilus Hfr conjugation Hfr recombination begins when an F+ plasmid with tra genes coding for mating pair formation iintegrates into the nucleoid to form an Hfr bacterium. There is a transfer of some chromosomal DNA, which may be exchanged for a piece of the recipient's DNA through homologous recombination, but not the ability to form a conjugation pilus and mating pairs., description Occasionally during spontaneous induction during the lysogenic life cycle, a small piece of bacterial DNA may sometimes be exchanged for a piece of the bacteriophage genome, which remains in the bacterial nucleoid. This piece of bacterial DNA replicates as a part of the bacteriophage genome and is put into each phage capsid. The bacteriophages are released, adsorb to recipient bacteria, and inject the donor bacterium DNA/phage DNA complex into the recipient bacterium where it inserts into its nucleoid., Horizontal Gene Transfer mechanisms conjugation, transduction types, A process in which an organism transfers genetic material to another organism that is not its offspring. benefit to bacteria, Horizontal Gene Transfer mechanisms transduction, Horizontal Gene Transfer mechanisms transformation, transformation description, A transfer of DNA from a living donor bacterium to a living recipient bacterium by cell-to-cell contact. In Gram-negative bacteria it typically involves a conjugation or sex pilus conjugative plasmid, transduction types, description Occasionally a bacteriophage capsid accidently assembles around a small fragment of bacterial DNA. When this bacteriophage infects another bacterium, it injects the fragment of donor bacterial DNA it is carrying into the recipient where it can subsequently be exchanged for a piece of the recipient's DNA by homologous recombination, A transfer of DNA from a living donor bacterium to a living recipient bacterium by cell-to-cell contact. In Gram-negative bacteria it typically involves a conjugation or sex pilus F+ conjugation, conjugation description A transfer of DNA from a living donor bacterium to a living recipient bacterium by cell-to-cell contact. In Gram-negative bacteria it typically involves a conjugation or sex pilus, transfer of R-plasmids This is the mechanism by which resistance plasmids R-plasmids) coding for multiple antibiotic resistance and conjugation pilus formation, are transferred from a donor bacterium to a recipient., Horizontal Gene Transfer definition A process in which an organism transfers genetic material to another organism that is not its offspring., A transfer of DNA from a living donor bacterium to a living recipient bacterium by cell-to-cell contact. In Gram-negative bacteria it typically involves a conjugation or sex pilus conjugative transposon Conjugative transposons carry the genes that enable mating pairs to form for conjugation. Therefore, conjugative transposons also enable mobilizable plasmids and nonconjugative transposons to be transferred to a recipient bacterium during conjugation., A transfer of DNA from a living donor bacterium to a living recipient bacterium by cell-to-cell contact. In Gram-negative bacteria it typically involves a conjugation or sex pilus mobilizable plasmids
