DNA Analysis in Forensics

The purpose of PCR is

• cutting DNA

• creating RFLPs

• amplifying/copying DNA

• reversing the charge of DNA

What do scientists use to cut DNA into smaller strands at specific locations?

• restriction enzymes

• scissors

• ligase

• agarose

Why do you use a new pipette tip on the micropipette every time you get a new sample?

• To avoid contaminating the other samples
• To use as many tools as you can.
• The pipette tips disappear after being used.
• None of these reasons

The computerized database used to store DNA information is: 

• AFIS
• NIBIN
• CODIS
• PDQ

The pattern of DNA fragments obtained by examining a person's unique sequence of DNA base pairs is termed?

• PCR

• Chromosome

• Electrophoresis

• DNA Fingerprinting

Which DNA strands move the fastest through the gel when the electricity is turned on?

• The long strands
• The short strands
• The medium strands
• They all move the same

What is the charge of DNA?

• positive
• negative
• neutral

Mitochondrial DNA is different from nuclear DNA because (CHOOSE TWO)...

[Bonus question. Do you remember from Biology class?]

• It is inherited only from the mother

• It is inherited only from the father

• It is in the shape of a circular loop

• It is in linear strands

Which suspect should be charged with the crime?

• Suspect 1

• Suspect 2

• Suspect 3

• None of these suspects

Restriction Enzymes . . . 

• cut DNA at precise locations
• help bacteria to pick up DNA
• move DNA through a gel
• copy DNA
