Question

which mode of genetic recombination is matched correctly with its description?
transduction—virus transfers genes from one bacteria to another
conjugation—involves splitting of one cell and results in two identical cells
binary fission—requires direct cell-to-cell contact of bacteria
transformation—uses a pilus to transmit genetic information between bacteria

Explanation:

• Transduction: In bacteria, transduction is indeed the process where a virus (bacteriophage) transfers genes from one bacterium to another.
• Conjugation: It involves direct cell - to - cell contact (using a pilus) for genetic transfer, not splitting to form identical cells. Binary fission is the asexual reproduction method where one cell splits into two identical cells.
• Binary fission: It is a form of asexual reproduction in bacteria (not a genetic recombination mode in the traditional sense of gene transfer between different bacteria cells as in conjugation, transduction, transformation) and does not require cell - to - cell contact for genetic transfer (it's just cell replication).
• Transformation: It is the uptake of free DNA from the environment by a bacterium, not using a pilus (pilus is for conjugation).

Answer:

transduction—virus transfers genes from one bacteria to another
