DNA Forensics and Genetic Genealogy

The purpose of PCR

• cutting DNA
• 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

Who invented the process of DNA fingerprinting?

• Jeffreys

• Dawson

• Rosalind

• Crick

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

• Thermonuclease

• Taq Polymerase

• DNA 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
