Transformation experiment was first performed by _____in____.

Options

A. Leaderberg and Tatum, E coli
B. Griffith, Streptococcus pneumoniae
C. Zinder and Lederberg, Salmonella
D. Linnaeus and Mc Carty, E. coli

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the first person to perform the transformation experiment and the organism involved in that experiment.

2. **Analyzing the Options**:
- Option A: Lederberg and Tatum, E. coli - This option refers to bacterial conjugation, not transformation.
- Option B: Griffith, Streptococcus pneumoniae - This option is significant as it relates to the transformation experiment.
- Option C: Zinder and Lederberg, Salmonella - This option refers to a different type of experiment (U-tube experiment).
- Option D: Linnaeus and McCarty, E. coli - This option is incorrect as it relates to a different field of study.

3. **Identifying the Correct Answer**: Frederick Griffith conducted the transformation experiment in 1928 using two strains of Streptococcus pneumoniae (smooth and rough strains). His experiment demonstrated that genetic material could be transferred between bacteria, which is the essence of transformation.

4. **Final Answer**: The transformation experiment was first performed by **Griffith** in **1928**.
