uestion 3: Why are STRs (short tandem repeats) preferred over VNTRs in modern DNA fingerprinting? Answer: Because STRs are shorter, easier to amplify via PCR, and provide highly discriminative power in forensic and paternity applications.
g specific regions in the genome that are highly variable among individuals, known as Variable Number Tandem Repeats (VNTRs) or Short Tandem Repeats (STRs). These regions are highly polymorphic, making them ideal for distinguishing one person from another.
