All of the following form the basis of DNA fingerprinting, except

Options

A. Degree of polymorphism
B. VNTR
C. Minisatellite
D. ESTs

Answer

To solve the question regarding the basis of DNA fingerprinting, we need to analyze the options provided and determine which one does not contribute to the DNA fingerprinting process. Here’s a step-by-step breakdown of the reasoning:

### Step 1: Understand DNA Fingerprinting
DNA fingerprinting is a technique used to identify individuals based on their unique DNA profiles. It relies on variations in DNA sequences among individuals.

### Step 2: Identify Key Components of DNA Fingerprinting
The components that are typically involved in DNA fingerprinting include:
- **Degree of Polymorphism**: Refers to the variations in DNA sequences among individuals. High polymorphism is crucial for distinguishing between different DNA samples.
- **VNTR Probes (Variable Number of Tandem Repeats)**: These are short sequences of DNA that can vary in number between individuals. They are essential for DNA profiling.
- **Mini Satellites**: These are longer repetitive sequences that also exhibit variability among individuals, making them useful for DNA fingerprinting.

### Step 3: Analyze the Given Options
The question mentions ESTS (Expanded Simple Tandem Repeats) as one of the options. While ESTS can provide information about specific sequences, they are not typically used for the purpose of DNA fingerprinting.

### Step 4: Conclusion
Based on the analysis, the component that does not form the basis of DNA fingerprinting is **ESTS**. Therefore, the answer to the question is that ESTS is the odd one out.

### Final Answer
**ESTS (Expanded Simple Tandem Repeats)** does not form the basis of DNA fingerprinting.
