Process of genetic mutation is

Options

A. Reversible
B. Irreversible
C. Partially reversibvle
D. Continuous.

Answer

### Step-by-Step Solution:

1. **Understanding Genetic Mutation**:
- Genetic mutations are changes in the DNA sequence of an organism. These changes can occur due to various factors, which can be intrinsic (internal) or extrinsic (external).

2. **Types of Mutations**:
- Mutations can alter the configuration and position of nucleotides, which are the building blocks of DNA. This alteration can lead to different types of mutations, such as point mutations, insertions, deletions, etc.

3. **Reversibility of Mutations**:
- The question asks about the reversibility of genetic mutations. Generally, mutations are considered irreversible because once a mutation occurs, it changes the original DNA sequence permanently.

4. **Exceptions to Irreversibility**:
- There are exceptions to this general rule, such as back mutations (or reverse mutations), where a mutation can revert to the original sequence. However, these are not common and do not apply to most mutations.

5. **Conclusion**:
- Therefore, the correct answer to the question regarding the process of genetic mutation is that it is generally **irreversible**, with the exception of back mutations.

### Final Answer:
The process of genetic mutation is **irreversible**.
