WebBacterial conjugation is the transfer of genetic material (plasmid) between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. Discovered … WebBacteria may have various types of surface structures. These include fimbriae, short protrusions found all over the surface of the bacterium; a flagellum, found at the back of the bacterium and used for propulsion; and a sex pilus, used to grab on to other bacteria for exchange of genetic material.

WebBacterial Transduction Transduction is the process of transfer of genes from the recipient to the donor through bacteriophage. Transduction is of two types: Generalized Transduction Specialized Transduction … WebIf the new DNA matches with a homologous region of the recipient cell's chromosome, it will exchange DNA material similar to the actions in bacterial recombination. Specialized transduction. Specialized …

WebThe bacterial genetic material is a single, circular molecule of DNA not arranged into a chromosome. Bacteria can have several shapes (e.g., rod shaped; filamentous; spiral shaped). Many bacteria cause disease by producing toxins. Bacterial infections that cause human illness can be prevented by vaccines or can be cured by antibiotics.

WebBacteria divide very rapidly. The doubling time is also called generation time and it may be as low as 20 minutes. Bacteria mainly reproduce by asexual reproduction but do not exhibit true sexual reproduction as they do not produce diploid phase. Thus, meiosis is lacking.
