The technique of gel electrophoresis was developed by

Options

A. a.Kary Mullis
B. b.J.S Chamberlain
C. c. A.Tiselius
D. d.F.Sanger

Answer

**Step-by-Step Solution:**

1. **Understanding Gel Electrophoresis**: Gel electrophoresis is a laboratory technique used to separate mixtures of DNA, RNA, or proteins according to their size and charge. This technique allows scientists to analyze and manipulate these biomolecules.

2. **Historical Context**: The development of gel electrophoresis dates back to the early 20th century. The foundational principles of electrophoresis were established in 1931.

3. **Identifying Key Contributors**: Among the options provided:
- **Cary Mullis** is known for inventing the Polymerase Chain Reaction (PCR), which is a method for amplifying DNA.
- **J.S. Chamberlain** focused on gene therapy, particularly related to muscular dystrophy.
- **Frederick Sanger** is recognized for his work on the structure of proteins, including insulin.
- **Ann Tessalius** (often referred to as Antesalius) is credited with the development of gel electrophoresis.

4. **Conclusion**: Based on the historical context and contributions of the individuals listed, the correct answer to the question of who developed the technique of gel electrophoresis is **Ann Tessalius**.

**Final Answer**: The technique of gel electrophoresis was developed by Ann Tessalius.
