Forensics DNA Fingerprinting Quizizz

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 second 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

T or F: The second step to making a DNA Fingerprint is to cut the DNA into different sized pieces.

• True

• False

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

Three tools are used to make a DNA fingerprint - which one is like scissors that cuts DNA at a particular sequence?

• PCR Machine

• Restriction Enzyme

• DNA Ligase

• Gel Electrophoresis machine

T or F: Restriction Enzyme is like scissors that cuts DNA at a particular sequence

• True

• False

Three tools are used to make a DNA fingerprint - which one is like a biological copy machine, making thousands of copies of each piece of DNA?

• PCR Machine

• Restriction Enzyme

• DNA Ligase

• Gel Electrophoresis machine

Three tools are used to make a DNA fingerprint - which one separates pieces of DNA by size?

• PCR Machine

• Restriction Enzyme

• DNA Ligase

• Gel Electrophoresis machine

Why do DNA pieces move from the top of the Gel towards the bottom?

• there is an electric charge in the gel, (+) at the top, which repels the (+) DNA molecules

• there is an electric charge in the gel, (-) at the top, which repels the (+) DNA molecules

• there is an electric charge in the gel, (-) at the top, which repels the (-) DNA molecules

• there is an electric charge in the gel, (+) at the top, which repels the (-) DNA molecules
