Why is DNA Fingerprinting called a 'fingerprint'?

• All of a person's DNA is found in their fingers

• A person's DNA Fingerprint looks the same as a person's finger fingerprint

• Everyone's finger fingerprint is unique, just as everyone's DNA Fingerprint is unique

• The tool used to make a DNA Fingerprint is called 'The DNA Fingerprint Machine'

What is the first step to making a DNA Fingerprint?

• Make millions of copies of the DNA

• Cut the DNA into different sized pieces

• Separate the DNA pieces by size

• Compare DNA fingerprints, find a match

What is the third step to making a DNA Fingerprint?

• Make millions of copies of the DNA

• Cut the DNA into different sized pieces

• Separate the DNA pieces by size

• Compare DNA fingerprints, find a match

• PCR Machine

• Restriction Enzyme

• DNA Ligase

• Gel Electrophoresis machine
