Bacterial recombination involves DNA transfer from a donor to a recipient, enhancing bacterial functionality like antibiotic resistance. The main methods are transformation, conjugation, and transduction. Transduction, involving viruses, is a key tool for molecular biologists. Viruses, as obligate parasites, replicate via lysogenic or lytic pathways. Transduction can be generalized or specialized, with the latter used to introduce specific genes into host cells. The video concludes with a summary of these recombination methods.
