The first person to isolate DNA from the nucleus of pus cells was Friedrich Miescher. Here are the steps he took:

1. Miescher began his work by collecting pus from discarded surgical bandages. The pus contained a high number of white blood cells, which are rich in nuclei.

2. He then treated the cells with a solution of sodium sulfate and sodium chloride to break down the proteins and lipids in the cell membranes, leaving only the nuclei.

3. Miescher further treated the nuclei with an alkaline solution and then with acid, which caused the nuclei to break down and release their contents.

4. Among the substances released was a substance Miescher called "nuclein" because it came from the nuclei. This substance was high in phosphorus and resistant to protein-digesting enzymes, which led Miescher to believe it was a new type of molecule.

5. Later research confirmed that "nuclein" was indeed DNA. Thus, Friedrich Miescher was the first person to isolate DNA, although he did not fully understand what he had discovered at the time.
