Transduction in bacteria was discovered by

Options

A. Zinder and Lederberg
B. Wollman and Jacob
C. Herelle and Twort
D. Lederberg and Tatum.

Answer

**Step-by-Step Solution:**

1. **Understanding Transduction**: Transduction is a process in bacteria where genetic material is transferred from one bacterium to another via a bacteriophage (a virus that infects bacteria). This process can lead to genetic variation among bacterial populations.

2. **Identifying the Discoverers**: The question asks who discovered transduction in bacteria. Historical context is important here, as it helps to identify the right scientists associated with this discovery.

3. **Reviewing the Options**:
- **Option 1: Zinder and Lederberg**: They are known for their work on transduction in bacteria, specifically in the year 1951.
- **Option 2: Vollmann and Jacob**: These scientists contributed to the understanding of high-frequency recombination (HFR) genes, not transduction.
- **Option 3: Harrell and Twatt**: They are known for their independent discovery of bacteriophages, but not transduction.
- **Option 4: Lederberg and Totem**: They are associated with conjugation, another form of genetic exchange in bacteria, but not transduction.

4. **Conclusion**: Based on the information reviewed, the correct answer to the question "Transduction in bacteria was discovered by" is **Zinder and Lederberg**.

**Final Answer**: Zinder and Lederberg
