Virus-mediated transfer of host DNA from one cell to another cell is known as:
Show Hint
- Transduction
- Integration
- Transformation
- Transcription
The Correct Option is A
Solution and Explanation
Step 1: Understanding transduction. Transduction is a process in which a bacteriophage (virus) transfers genetic material from one bacterial cell to another. This occurs when a phage accidentally packages host DNA instead of viral DNA and injects it into another bacterium.
Step 2: Types of transduction.
- Generalized transduction: Any bacterial gene can be transferred.
- Specialized transduction: Only specific bacterial genes near the phage integration site are transferred.
Step 3: Why other options are incorrect.
- (B) Integration: Refers to viral DNA integrating into the host genome, not transferring host DNA.
- (C) Transformation: Involves uptake of free DNA from the environment by bacteria, not virus-mediated.
- (D) Transcription: The process of RNA synthesis from DNA, unrelated to gene transfer.
