8.4 DNA Fingerprinting Flashcards
1
Q
PCR (Polymerase Chain Reaction
A
An enzyme used to make copies from small amounts of DNA
2
Q
DNA is cut into fragments using?
A
Restriction Enzymes, which act like scissors
3
Q
What is used to make up a finger print?
A
VNTR’s (Variable Number Tandem Repeats)
4
Q
What separates DNA fragments on basis of their sizes?
A
Gel Electrophoresis
5
Q
What are the basic steps in DNA fingerprinting?
A
Isolate DNA from tissues, cut DNA into small fragments with different sizes, and separating the DNA fragments to identify different sized pieces
6
Q
How do you identify different individuals using DNA fingerprinting?
A
Because of their unique fragments
7
Q
What do reaction enzymes cut?
A
They cut around DNA sequences called VNTR’s
8
Q
Gel Electrophoresis separates what?
A
DNA fragments based on their sizes
