STR Analysis (Short Tandem Repeat Analysis)

Short Tandem Repeat (STR) analysis is a technique used in genetics to examine specific areas of DNA where short sequences of nucleotides are repeated. These repeats can vary in length among individuals, making them useful for identification purposes, such as in forensic science and paternity testing. By analyzing these variations, scientists can create a unique DNA profile for a person, helping to establish identity or familial relationships. STR analysis is highly reliable and is a cornerstone of modern genetic testing and forensic investigations.
