DNA analysis techniques

DNA analysis techniques involve examining an individual’s genetic material to identify or compare DNA. Common methods include PCR (Polymerase Chain Reaction), which amplifies tiny DNA samples to detectable levels, and gel electrophoresis, which separates DNA fragments by size for comparison. Sequencing determines the exact order of bases in a DNA segment, revealing genetic information. Other techniques like STR analysis focus on specific regions that vary among individuals, useful in forensic identification. These methods help in forensic investigations, paternity testing, and genetic research by providing accurate, detailed insights into genetic makeup.
