Verified step by step guidance

Understand that DNA contains unique sequences that vary between individuals, making it a powerful tool for identification.

Recognize that obtaining a small amount of a person's DNA allows scientists to analyze specific regions known as genetic markers or short tandem repeats (STRs).

Learn that DNA fingerprinting involves comparing these genetic markers to create a unique profile for an individual.

Note that this technique is widely used in forensic science, paternity testing, and identifying individuals in various biological samples.

Differentiate this application from other options like measuring protein synthesis, counting chromosomes, or observing mitosis, which do not primarily rely on small DNA samples for identification.
