1. DNA Fingerprint Analysis
An Overview
DNA fingerprinting is a technique used to identify individuals by analyzing their DNA. It is based on the fact that each person’s DNA is unique, except for identical twins.
The steps involved in DNA fingerprint analysis are as follows:
- DNA is extracted from the sample.
- The DNA is cut into fragments using restriction enzymes.
- The fragments are separated by gel electrophoresis.
- The fragments are transferred to a nylon membrane.
- The membrane is hybridized with a labeled probe that is complementary to the DNA fragments.
- The labeled probe binds to the complementary DNA fragments, and the resulting pattern is visualized.
DNA fingerprinting has a wide range of applications, including:
- Forensic science
- Paternity testing
- Medical diagnostics
- Genealogical research
