What is a DNA Fingerprint?

Back

The pattern of DNA fragments obtained by examining a person's unique sequence of DNA pairs.

Front

How can DNA Fingerprinting be used in forensics?

Back

It can identify individuals involved in a crime by matching DNA found at a crime scene with that of suspects.

Front

What is the significance of genetic markers in DNA Fingerprinting?

Back

Genetic markers are specific sequences in DNA that can be used to differentiate between individuals.

What role does PCR play in DNA Fingerprinting?

Back

Polymerase Chain Reaction (PCR) amplifies small amounts of DNA to create enough for analysis.
