The process of DNA staining typically involves several steps: 1. Fixation: Cells or tissues are fixed to preserve their structure and to make the DNA accessible to dyes. 2. Permeabilization: This step allows the dye to penetrate the cell membrane or nuclear envelope. 3. Staining: The sample is incubated with the DNA-specific dye. 4. Washing: Excess dye is washed away to reduce background staining. 5. Visualization: The stained sample is examined under a microscope, often using specific filters if fluorescent dyes are used.
