DNA extraction is a process that involves the isolation and purification of DNA from a biological sample. There are several synonyms that can be used in place of DNA extraction, which include DNA isolation, DNA purification, DNA extraction and purification, or simply DNA extraction. These terms all refer to the same basic process of separating and cleaning DNA from the other components of a biological sample. DNA extraction is a critical step in many research applications, including genetic sequencing, forensic analysis, and disease diagnosis and treatment. Accurate and efficient DNA extraction techniques are essential for obtaining high-quality DNA samples that can be used in these and other applications.
