Which of the following viruses will be useful for transduction?
A. T2 phage
B. T4 phage
C. T7 phage
D. Lamda phage
Answer:D
Which of the following viruses will be useful for transduction?
A. T2 phage B. T4 phage C. T7 phage D. Lamda phage
Explanation: T phages mainly undergo lytic cell cycle, while lamda phages have lysogenic cell cycle. For transduction to occur, the viral genome must integrate within the nucleoid else it will never incorporate bacterial gene within itself. Thus, only lamda phage will be able to help in transduction.
