DNA preservation techniques

DNA preservation techniques aim to protect genetic material from degradation. Common methods include refrigeration and freezing, which slow down enzyme activity that breaks down DNA. Desiccation (drying) removes moisture that promotes decay. Chemical preservation involves using substances like ethanol or specific buffers that stabilize DNA molecules. In ancient samples, dehydration and controlled environments help maintain DNA integrity over time. Proper preservation is crucial for accurate analysis and long-term storage, ensuring the DNA remains intact for research or identification purposes.
