DNA fingerprinting, also known as DNA profiling, is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA.

Here's how it works, step by step:

1. **Sample Collection**: A sample of body tissue or fluid such as hair, skin, blood, or semen is collected. This sample contains cells, and most cells in our body contain a complete set of our DNA.

2. **DNA Extraction**: The DNA is then extracted from the cells in the sample. This is usually done by breaking open the cell and the nucleus with a series of chemical reactions.

3. **DNA Fragmentation**: The extracted DNA is then cut into smaller fragments using special enzymes known as restriction enzymes. These enzymes cut the DNA at specific sequences.

4. **Separation of DNA fragments
