Answer 1

Step 1: What is DNA Fingerprinting?
DNA fingerprinting is a molecular biology technique used to identify individuals based on their unique DNA profiles. It is a technique that compares specific regions of the DNA sequence that are highly variable among individuals.
Step 2: Uses of DNA Fingerprinting.
- Forensic Science: It is widely used in criminal investigations to match biological samples (blood, hair, etc.) to suspects.
- Paternity Testing: DNA fingerprinting can confirm biological relationships between individuals, such as parent-child relationships.
- Genetic Studies: It helps in mapping genetic diseases and identifying the genetic makeup of individuals or populations.
- Identification: It is used in identifying individuals in cases of missing persons, immigration, and animal identification.
