Mutation in which a part or complete gene is removed is

Options

A. Deletion
B. Inversion
C. Translocation
D. Duplication

Answer

To solve the question "Mutation in which a part or complete gene is removed is," we will analyze the options provided and determine the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding the Options**: The question provides four options:
- A) Deletion
- B) Inversion
- C) Translocation
- D) Duplication

2. **Analyzing Each Option**:
- **Duplication**: This refers to a mutation where a segment of DNA is copied, resulting in multiple copies of that segment. This does not involve the removal of any genetic material.
- **Translocation**: This is a chromosome abnormality caused by the rearrangement of parts between non-homologous chromosomes. It does not involve the removal of genetic material but rather a rearrangement.
- **Inversion**: This mutation involves a segment of a chromosome being reversed end to end. Again, this does not involve the removal of genetic material.
- **Deletion**: This mutation involves the loss of a part or complete gene from a chromosome. It is characterized by the removal of a segment of DNA during DNA replication.

3. **Identifying the Correct Answer**: Based on the definitions and characteristics of each mutation type, the correct answer is:
- **Deletion** (Option A), as it specifically refers to the removal of part or complete gene from the DNA sequence.

### Final Answer:
The mutation in which a part or complete gene is removed is **Deletion**.
