DNA amplification is a powerful technique that has had an immense impact on scientific research in the past 2 decades. While polymerase chain reaction (PCR) is still the most popular method, alternative methods of DNA amplification are constantly being developed. In addition, the extraordinary versatility of PCR has led to its use in novel ways that have opened new avenues of research. These novel methods for DNA amplification and the versatility of PCR are highlighted in DNA Amplification: Current Technologies and Applications.
Expand VNTR and describe its role in DNA fingerprinting.

Explanation

**Step-by-Step Solution:**

1. **Understanding VNTR**: VNTR stands for Variable Number of Tandem Repeats. These are specific sequences in the DNA that are repeated a variable number of times in different individuals.

2. **Structure of VNTR**: The term "tandem repeats" refers to sequences of DNA that are repeated in a head-to-tail manner. For example, a sequence like "ATA" can be repeated multiple times, such as "ATAATAATAATA..." up to hundreds or thousands of times.

3. **Location of VNTRs**: VNTRs are often found in non-coding regions of the DNA, particularly near telomeres, which are the ends of chromosomes.
