DNA Fingerprinting

What does PCR stand for?

• Polymerase Chronic Reagent
• Principle Chorionic Reliability
• Polymerase Chain Reaction
• Probably Cannot React

In preparation for an electrophoresis procedure, enzymes are added to DNA in order to

• convert the DNA into gel

• cut the DNA into fragments

• change the color of the DNA

• produce longer sections of DNA

Gel electrophoresis is used to separate DNA fragments on the basis of which property?

• size

• color

• functions

• chromosomes

Which DNA fragment bands move faster and farther in a gel electrophoresis? 

• there is no way to tell 
• the largest ones
• the smallest ones
• none of these

Why do the fragments of DNA in gel electrophoresis travel away from the negative electrode?

• DNA is negatively charged so attracted to the positive end of the unit
• DNA is positively charged to attracted to the negative end of the unit
• the agarose gel in negatively charged
• the agarose gel is positively charged

Which suspect should be charged with the crime?

• Suspect 1

• Suspect 2

• Suspect 3

• None of these suspects

What is the structure of DNA?

• double helix
• ladder
• twisted helix
• double ladder

Why type of evidence is DNA?

• Class
• Trace
• Individual
• Direct

What process is used to determine if two DNA samples match?
