NEET BIOLOGY

Detailed explanation-1: -In conjugation, DNA is transferred from one bacterium to another. After the donor cell pulls itself close to the recipient using a structure called a pilus, DNA is transferred between cells. In most cases, this DNA is in the form of a plasmid.

Detailed explanation-2: -Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. This takes place through a pilus. It is a parasexual mode of reproduction in bacteria.

Detailed explanation-3: -Transduction is the transfer of DNA from one bacterium to another by means of a bacteria-infecting virus called a bacteriophage.

Detailed explanation-4: -Most bacteria rely on binary fission for propagation. Conceptually this is a simple process; a cell just needs to grow to twice its starting size and then split in two.
