DNA Fingerprinting

A method of amplifying (duplicating) small amounts of DNA evidence for use in investigation, testing, etc.

• STRs

• PCR

• Intron

• Exon

According to the gel electrophoresis results shown, which suspect committed the crime?

• Suspect 1

• Suspect 2

• Suspect 3

• not enough data to tell

The table shows the STR alleles of a set of parents for a specific gene. Based on the STRs of the mother and father, which of the following is NOT a possible STR combination for the offspring?

• 11, 13

• 13, 13

• 12, 11

• all are possible combinations

True or False?

Since identical twins have the EXACT same DNA, they also have the EXACT same fingerprints.

• True

• False

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 

Based on these results whose blood was found in the blood stain at the crime scene?

• Bob

• Sue

• John

• Lisa

The computerized database used to store DNA information is: 

• AFIS

• NIBIN

• CODIS

• PDQ

Which DNA strands move the fastest through the gel when the electricity is turned on?

• The long strands

• The short strands

• The medium strands

• They all move the same

This form of DNA typing uses heat to unzip DNA molecules.

• CODIS

• RFLP

• PCR

Type of DNA that varies most among individuals and is used to create DNA fingerprints.

• non-coding DNA

• coding DNA

• Deoxyribose

• hydrogen bonds
