Gel Electrophoresis & DNA

What is the purpose of PCR?

• Create many copies of DNA fragments

• Create a DNA fingerprint

• Remove DNA from a sample

• Cut the DNA into smaller pieces

DNA profiling works because

• Most genes are dominant

• All organisms contain RNA

• The most important genes are different among most people

• No two people, except identical twins, have exactly the same DNA

Investigator's run unknown DNA profiles through _________ in order to hopefully find a match to a known person's DNA profile.

• AFIS

• BBQ

• CODIS

• PDQ

What process is used to separate fragments of DNA?

• Restriction mapping

• Polymerase chain reaction

• Sanger sequencing

• Gel electrophoresis

Which is the primary purpose of using restriction enzymes in gel electrophoresis?

• It allows the strands of DNA to be cut into various lengths for testing
• It restricts the number of base pairs that can be tested in a sample
• It makes the testing simpler by moving the strands into the gel faster
• It charges the DNA strands

Which suspect is likely guilty?

• Suspect #1
• Suspect #2
• Suspect #3
