The HIV virion contains a protein called Reverse Transcriptase. HIV infects some immune cells of humans. When HIV infects a cell, it immediately takes over the cell machinery to make many copies of itself, and the cell lysis within about 20 minutes. One major advantage of studying genetics in bacteria is how quickly they reproduce. In transduction, bacteriophage carry DNA from one bacterium to another.
R factors are plasmids that encode antibiotic resistance.
They lack an origin of replication. Transformation Transduction Conjugation followed by meiosis F' mediated DNA transfer 5. The F' factor can be either free or integrated into the bacterial chromosome. Following complete transfer of the F' factor, the recipient bacterium, formerly considered female, becomes male. Bacteria with an integrated F' factor typically transfer the entire F' sequence to the recipient.
