STR analysis is a powerful tool used in forensic analysis. It helps distinguish between individuals based on their unique DNA profiles. Our DNA contains short tandem repeats, which are sequences of nucleotides repeated in tandem. These repeats vary in length among individuals.
By analyzing specific STR regions in an individual’s nuclear DNA, forensic experts can create a genetic fingerprint that is highly discriminating.
STR analysis plays a crucial role in solving crimes. By comparing DNA samples from crime scenes to suspects, investigators can link or exclude individuals. In scientific research and medical labs, STR analysis verifies the authenticity of human cell lines and ensures sample quality. STRs help determine biological relationships, such as paternity or maternity.
Researchers continue to refine STR analysis methods, improving accuracy and expanding its applications. Next-generation sequencing and advanced statistical tools enhance our ability to extract valuable information from STR data.
