• creating RFLPs
• amplifying/copy DNA
• reversing the charge of DNA

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

What enzyme is used during PCR to pair complementary bases to the template strand?

• Thermonuclease
• Helicase
• DNA Polymerase
• RNA Polymerase

How do scientists cut DNA into smaller strands?

• 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
