Question

question 23
which of the following is not true of conjugation?
a the donor retains a copy of the transferred genes
b transfers genes for drug resistance
c transfers genes for enzymes and adher molecules
d involves direct contact between cells
e involves the action of bacteriophage

Explanation:

Conjugation is bacterial gene transfer via direct cell contact (pilus). Donors retain transferred genes (copying), transfer drug resistance (plasmids), enzymes/adhesins. Bacteriophages are for transduction, not conjugation.

Answer:

E. Involves the action of bacteriophage
