Which statement is correct for bacterial transduction?

1. Transfer of some genes from one bacteria to another bacteria through virus
2. Transfer of genes from one bacteria to another bacteria by conjugation
3. Bacteria obtains its DNA directly
4. Bacteria obtains its DNA from other external source

Correct answer: Transfer of some genes from one bacteria to another bacteria through virus

Solution

Bacterial transduction is the transfer of bacterial genes from one bacterium to another through a bacteriophage (virus). This distinguishes it from conjugation, which requires direct contact between bacteria.
