DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical methods. The first isolation of DNA was done in 1869 by Friedrich Miescher. Currently it is a routine procedure in molecular biology or forensic analyses.

Here are the basic steps involved in DNA isolation:

1. **Cell Lysis**: The first step in DNA isolation is the breaking down of the cell wall or membrane to release the cell contents. This is done using a lysis buffer, which breaks down the cell membrane.

2. **Protein Removal**: The next step is to remove the proteins from the cell contents. This is done using a protease (an enzyme that breaks down proteins) and a detergent, which further breaks down the cell membrane and denatures the proteins.

3. **DNA Precipitation**: The DNA is then precipitated out of the solution using alcohol. The DNA will clump together and can be seen as a stringy white substance.

4. **DNA Washing**: The DNA is then washed to remove any remaining impurities. This is usually done using a high salt buffer.

5. **DNA Rehydration**: The final step is to rehydrate the DNA in a small volume of water or buffer. This makes the DNA easier to work with in future experiments.

This is a simplified explanation of the process. The exact steps and reagents used can vary depending on the type of cells being used and the desired quality and quantity of DNA.
