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:

• For "transduction": Transduction is defined as the process where a virus (bacteriophage) transfers genetic material from one bacterium to another. This matches the description.
• For "conjugation": Conjugation involves direct cell - to - cell contact (via a pilus) to transfer genetic material, not cell splitting. Cell splitting resulting in two identical cells is binary fission.
• For "binary fission": Binary fission is the asexual reproduction of a single cell into two identical daughter cells, it does not require cell - to - cell contact (that's conjugation).
• For "transformation": Transformation is the uptake of foreign DNA from the environment by a bacterium, not the use of a pilus (conjugation uses a pilus).

Answer:

A. transduction—virus transfers genes from one bacteria to another
