Current technologies in forensic DNA analysis
Short tandem repeat (sSTR)analysis
STR analysis remain the gold standard for forensic DNA typing. This technique examine specific regions of DNA where short sequences repeat a variable number of times. The pattern of these repeats create a unique profile that can be compared against reference samples or database entries.
Y STR and mitochondrial DNA analysis
When traditional STR analysis is challenge, analysts may turn to specialized techniques. Y STR analysis examine markers on the y chromosome, which is pass unchanged from father to son. This approach is peculiarly useful for sexual assault cases with mixed male and female DNA.
Mitochondrial DNA analysis examine DNA inherit solely from the mother. This technique work easily with degraded samples or those with limited nuclear DNA, such as hair shafts without roots or old bones.
Next generation sequencing (nNGS)
NGS technologies are revolutionized forensicDNAa analysis by provide more comprehensive genetic information than traditional methods. These platforms can simultaneously analyzestarssSNPsp(( single nucleotide polymorphism)), and other genetic markers, extract more information from challenge samples.
