Answer:
The correct answer is option third - transcription.
Explanation:
Bacteria have evolved three ways to introduce DNA molecule into other bacteria cells and increase there genetic diversity which is - transformation, transduction, and conjugation.
Transformation is a process of gene transfer horizontally by which some bacteria introduce foreign genetic material from the outer environment.
Transduction is the process of introducing a bacterial genome into another with the help of the virus-like bacteriophage.
Conjugation is the process of the gene transfer from the donor to a recipient with the help of pilus.
Thus, the correct answer is option third - transcription.
