DNA testing techniques

DNA testing techniques analyze a person’s genetic material to identify specific patterns or markers. Methods like PCR (Polymerase Chain Reaction) amplify small amounts of DNA, making it easier to examine. STR (Short Tandem Repeat) analysis looks at specific DNA regions that vary between individuals, useful for forensic identification and paternity testing. Sequencing reads the exact order of nucleotides to detect mutations or genetic conditions. All these techniques rely on comparing DNA samples to known references or databases, helping in applications like crime solving, ancestry determination, and health diagnostics.
