Match the following:
(A) VNTR ---- p. Largest gene
(B) Introns and Exons --- q. DNA fingerprinting
(C) Dystrophin --- r. Bulk DNA
(D) Satellite DNA --- s. Splicing

Options

A. (A) - r, (B) -s, (C)- p, (D)- q
B. (A)- q, (B) - s, (C)- p, (D)-r
C. (A) - q, (B)- p, (C) - s, (D)-r
D. (A)- s, (B)-p, (C)-q,(D)-r

Answer

To solve the matching question, we need to analyze each item in column A and match it with the appropriate item in column B. Here’s the step-by-step solution:

1. **VNTR (Variable Number of Tandem Repeats)**:
- VNTRs are sequences in DNA that consist of repeating units. They are crucial for DNA fingerprinting, which is a technique used to identify individuals based on their unique DNA patterns.
- **Match**: VNTR - q (DNA fingerprinting)

2. **Introns and Exons**:
- Introns are non-coding regions of DNA that are not expressed in the final protein product, while exons are coding regions that are expressed. The process of splicing involves removing introns and joining exons together to form mature mRNA.
- **Match**: Introns and Exons - s (Splicing)

3. **Dystrophin**:
- Dystrophin is known as the largest gene in humans, consisting of around 79 exons and spanning approximately 2.3 million base pairs. It plays a critical role in muscle function.
- **Match**: Dystrophin - p (Largest gene)

4. **Satellite DNA**:
- Satellite DNA consists of repetitive sequences and is found in regions such as telomeres and centromeres. It is considered bulk DNA due to the large amounts of repetitive sequences present.
- **Match**: Satellite DNA - r (Bulk DNA)

Now, compiling all the matches, we have:
- (A) VNTR ---- q (DNA fingerprinting)
- (B) Introns and Exons ---- s (Splicing)
- (C) Dystrophin ---- p (Largest gene)
- (D) Satellite DNA ---- r (Bulk DNA)

**Final Matches**:
- A - q
- B - s
- C - p
- D - r
