Select the incorrect statement.

Options

A. DNA from single cell is enough to perform DNA fingerprinting analysis
B. DNA fingerprinting has much wider applications in determining population and genetic diversities
C. The VNTR belongs to a class of satellite DNA referred to as minisatellite
D. DNA fingerprint can be used to differentiate monozygotic twins

Answer

To solve the question of identifying the incorrect statement regarding DNA fingerprinting, we will analyze each of the provided statements step by step.

### Step-by-Step Solution:

1. **Understanding DNA Fingerprinting**:
- DNA fingerprinting is a technique used to identify individuals based on their unique DNA profiles. It involves comparing specific regions of DNA that vary greatly among individuals.

2. **Analyzing the Statements**:
- **Statement 1**: "DNA from a single cell is enough to perform DNA fingerprinting analysis."
- This statement is **correct**. DNA can be extracted from a single cell, and even a small sample, such as a hair follicle, can provide sufficient DNA for analysis.

- **Statement 2**: "DNA fingerprinting has much wider application in determining population or genetic diversity."
- This statement is also **correct**. DNA fingerprinting is widely used in studies of genetic diversity and population genetics to understand lineage and ancestry.

- **Statement 3**: "The VNTR belongs to a class of satellite DNA referred to as mini-satellite."
- This statement is **correct**. Variable Number Tandem Repeats (VNTRs) are indeed classified as mini-satellites, which are repetitive sequences in the DNA that can be used as markers in DNA fingerprinting.

- **Statement 4**: "DNA fingerprinting can be used to differentiate monozygotic twins."
- This statement is **incorrect**. Monozygotic twins originate from a single zygote and share identical genetic material. Therefore, their DNA fingerprints will be the same, making it impossible to differentiate between them using DNA fingerprinting.

3. **Conclusion**:
- The incorrect statement among the options provided is **Statement 4**. DNA fingerprinting cannot differentiate between monozygotic twins due to their identical genetic makeup.

### Final Answer:
The incorrect statement is: **"DNA fingerprinting can be used to differentiate monozygotic twins."**
