DNA restriction enzymes

• are used to repair DNA

• are involved in DNA synthesis

• restrict DNA from being amplified

• cut DNA into fragments of different lengths

A method of separating molecules, such as DNA, according to their size and electrical charge.

• Electrophoresis

A method used to rapidly make multiple copies of a specific segment of DNA.

• PCR (Polymerse Chain Reaction)

• Electrophoresis

• DNA Probe

Before doing gel electrophoresis, the DNA to be test must be cut into different sized fragments by:

• DNA Ligase

• DNA Polymerase

• Restriction Enzymes

• Primase

DNA is ___________ charged

• negatively

• positively

If base-pairing rules state that Adenine always pairs with Thymine, and Cytosine pairs with Guanine, what would be the complementary strand to ACGGT?

• ACGGT
• TGGCA
• TGCCA
• ACCGT

Which suspect is linked to the crime scene by this DNA analysis?

• Suspect A

• Suspect C

• Suspect D
