The correct option is (A) binary fission
Binary Fission
Binary fission is an asexual method of reproduction in which one bacterium divides into two daughter cells which are clones, i.e. they are genetically and morphologically identical to each other and the parent bacterium.
When prokaryotic organisms reproduce, this is their main strategy. Without the cell forming a spindle mechanism, binary fission takes place. A single DNA molecule initiates replication in this process, attaching each copy to different regions of the cell membrane as it goes. The original (real) and replicated chromosomes separate when the cell begins to be dragged apart.
Conjugation
Conjugation is the transfer of plasmid DNA from one bacterial cell to the other bacterial cell through the formation of a conjugation tube.
The process of conjugation involves putting two bacteria in touch with one another in order to transfer genetic material. Lederberg and Tatum presented this approach. They developed the idea of conjugation after learning that the F-factor can travel between E. coli cells. Different bacterial species carry different conjugal plasmids. Conjugation is done in a number of steps:
- Establishment of mating pairs
- DNA exchange
- Conjugal DNA synthesis
- Maturation
Transduction
Transduction is a process in which the virus transfers the genetic material from one bacterium to another.
Bacteriophages that infect bacteria multiply in this manner (through the process of transduction) using host cells, and occasionally while assembling, they incorporate bacterial DNA. The bacterial genome that these viruses carry may later be integrated into the host genome when they infect fresh bacterial cells. In genetic engineering, transduction is frequently employed to introduce foreign DNA into the host cell.
Final Answer
Clone formation occurs in the bacteria in binary fission.
