DNA Forensics Test

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

Restriction Enzymes . . . 

• cut DNA at precise locations
• help bacteria to pick up DNA
• move DNA through a gel
• copy DNA

Collection of DNA fragments that can be used to identify genetically unique individuals

• Amplify

• DNA Ladder

• DNA Fingerprint

• DNA Analysis

Bob was found dead in his home.  Crime scene analysis showed signs of a struggle.  Blood was collected from the crime scene, the victim, and three suspects.  Which suspect likely committed the crime? 

• Sue
• Lisa
• John
• None of these

DNA fingerprinting 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 

Which sequence of DNA bases would pair with this partial strand

ATG TGA CAG

• ATG TGA CAG

• TAC ACT GTC

• GTA AGT GAC

• CAT TCA CTG

In the nucleus of most human body cells, there are

• 23 pairs of chromosomes

• 46 pairs of chromosomes

• 92 chromosomes

• None of these choices

This process of DNA fingerprinting separates the DNA fragments through a gel using an electrical current.

• DNA Extraction

• Polymerase Chain Reaction

• Gel Electrophoresis

• DNA Replication

The process of DNA fingerprinting was invented by:
