Bacteria can achieve genetic variation through three main processes: transformation, conjugation, and transduction. In transformation, bacteria uptake free DNA from their environment, which can originate from lysed cells. Conjugation involves the direct transfer of DNA between two bacterial cells through a physical connection called a pilus. Transduction occurs when bacteriophages (viruses that infect bacteria) transfer genetic material from one bacterium to another, facilitating the exchange of genes. These mechanisms enhance genetic diversity and adaptability in bacterial populations.
The most important source of variability in bacteria is mutation.
Conjugation is a mechanisms used by bacteria to move genes between cells by exchanging a circular extrachromosomal DNA with each other. Transduction is when viruses that infect bacteria accidentally take some bacterial genes with them into a new cell that htey infect (kinda like STDs). Transformation is when a bacteria gets DNA from its environment.
Bacteria exchange genetic material, in the form of plasmids, through conjugation. Conjugation is achieved when a pili from once cell attaches to the cell wall of another cell..
change in phenotype of bacteria caused by the presece of foreign genetic material
This results in bacteria expressing human proteins or genes.
There are three main forms of horizontal transmission used to spread genes between members of the same or different species: conjugation (bacteria-to-bacteria transfer), transduction (viral-mediated transfer), and transformation (free DNA transfer).
The most important source of variability in bacteria is mutation.
Genetic engineering involves the use of recombinant DNA technology, the process by which a DNA sequence is manipulated in vitro, thus creating recombinant DNA molecules that have new combinations of genetic material

The process by which one strain of bacteria is apparently changed into another strain is called bacterial transformation. This process involves the uptake and expression of foreign DNA by bacteria, leading to genetic changes.
Bacteria are better suited for total genetic transformation because they have simple genomes and easily take up foreign DNA through processes like conjugation, transformation, and transduction. This makes it easier to manipulate and introduce new genetic material into bacteria for genetic engineering purposes.
Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or a bridge-like link between two cells. In bacteria, it is a parasexual way of reproduction. It's a horizontal gene transfer process, like transformation and transduction, but it doesn't entail cell-to-cell communication.
In the process of conjugation bacteria transfers its genetic material to an other bacteria by using sex pilli not any virus.
Prokaryotes have additional ways to evolve their genomes besides relying on relatively infrequent mutations. Through genetic recombination, individual prokaryotic cells can share DNA with other individual cells, not necessarily belonging to the same species.They can also exchange genetic material by transformation, transduction, and conjugation.In conjugation, plasmid DNA is transferred from cell to cell using something called a sex pilus. In transformation cells pick up DNA from their environment. Lastly, transduction is the transfer of genetic material from one cell to another using a virus.

Bacteria increase genetic variation through mechanisms such as mutation, horizontal gene transfer, and genetic recombination. Mutations can introduce new genetic variations, while horizontal gene transfer allows bacteria to exchange genetic material with other bacteria and acquire new genes. Genetic recombination, through processes like conjugation and transformation, also contributes to genetic diversity in bacteria.
