Detailed explanation-1: -Bacteria reproduce asexually by binary fission. They also show the exchange of DNA through conjugation, transformation and transduction. Bacteria are unicellular, microscopic organisms, which have been grouped as prokaryotes, which means these organisms lack a true nucleus.
Detailed explanation-2: -So, bacteria can’t reproduce sexually, but they can exchange genetic information with each other. Using a pilus, two bacteria make contact with each other and exchange genetic material. This is called conjugation. Some bacteria simply take up DNA which is floating around in their environment.
Detailed explanation-3: -Transduction occurs when a bacteriophage containing bacterial DNA infects a recipient bacterium and transfers this bacterial DNA to the recipient bacterial host cell. This transferred bacterial DNA may then be incorporated into the genome of the recipient bacterium.
Detailed explanation-4: -Bacterial conjugation, also referred to as bacterial sex, is a major horizontal gene transfer mechanism through which DNA is transferred from a donor to a recipient bacterium by direct contact.
Detailed explanation-5: -Binary Fission. Most bacteria rely on binary fission for propagation. Some Unusual Forms of Reproduction in Bacteria: Baeocyte production in the cyanobacterium Stanieria. Budding in bacteria. Intracellular offspring production by some Firmicutes.
