Clone formation occurred in the bacteria in

Options

A. Conjugation
B. Transduction
C. Binary fission
D. All of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Clones**: Clones are genetically identical organisms produced through asexual reproduction. This means that they arise from a single parent organism.

2. **Analyzing the Options**:
- **Conjugation**: This is a process of sexual reproduction in bacteria where genetic material is transferred from one bacterium to another through a structure called a sex pilus. Since this involves genetic exchange, it does not result in clones.
- **Transduction**: This is another method of genetic exchange in bacteria, where a bacteriophage (a virus that infects bacteria) transfers genetic material from one bacterium to another. Like conjugation, this process also involves genetic variation and does not produce clones.
- **Binary Fission**: This is a form of asexual reproduction in bacteria where a single parent cell divides into two identical daughter cells. Since the daughter cells are genetically identical to the parent, this process results in the formation of clones.

3. **Conclusion**: Since only binary fission leads to the formation of clones in bacteria, the correct answer to the question is **binary fission**.

**Final Answer**: Binary fission
