DNA fingerprinting involve identifying differences in some specific regions in DNA sequence called as :-

Options

A. Euchromatin
B. Repetitive DNA
C. Genophore
D. Heterochromatin

Answer

To solve the question regarding DNA fingerprinting, we need to identify the specific regions in DNA sequences that are involved in this process. Here’s a step-by-step breakdown of the solution:

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

**Hint:** Think about how each individual has a unique genetic makeup that can be analyzed.

### Step 2: Identify the Key Terms
The question asks for the specific regions in DNA sequences that are identified during DNA fingerprinting. The options provided are:
1. Eukaryotin
2. Repetitive DNA
3. Genophore
4. Heterochromatin

**Hint:** Focus on the terms that relate to DNA structure and function.

### Step 3: Analyze the Options
- **Eukaryotin:** Refers to the part of the chromosome that is lightly stained and represents the active genes. Not specifically related to fingerprinting.
- **Repetitive DNA:** This consists of non-coding regions that repeat multiple times in the genome. These regions are crucial for DNA fingerprinting as they show variability between individuals.
- **Genophore:** This term is used to describe the genetic material in prokaryotic cells, not relevant to DNA fingerprinting.
- **Heterochromatin:** This is the densely packed form of DNA, which is not typically the focus of DNA fingerprinting.

**Hint:** Consider which option relates to the variability that is the basis of DNA fingerprinting.

### Step 4: Conclusion
Based on the analysis, the correct answer is **Repetitive DNA**. This type of DNA contains sequences that are repeated and vary among individuals, making it essential for DNA fingerprinting.

**Final Answer:** Repetitive DNA
