Forensics Ch. 7 DNA Fingerprinting

What method uses an electric current to separate DNA fragments by size?

• DNA Splicing
• Gel electrophoresis
• DNA Fingerprint 
• Polymerase Chain Reaction

A molecule labeled with a radioactive isotope or dye used to locate a gene on a DNA molecule is

• Primer      
• Intron
• Genome
• DNA probe

The segment of a chromosome that contains the information used to produce a protein is a(n):

• Intron      
• DNA probe
• Gene
• Exon

The total amount of DNA in a cell is called the:

• genome 
• genetic library 
• DNA fingerprint 
• mass number

The process of DNA fingerprinting was invented by:

• Jeffreys 
• Roseland
• Crick
• Watson 

Most human cells have how many chromosomes?

• 23
• 24
• 36
• 46

The sides of the helix, referred to as the backbone of DNA, are made up of:

• paired sugar molecules
• base and phosphate molecules 
• sugar and phosphate molecules 
• paired nitrogenous bases 

Which example shows a correct complementary base pair?

• Cytosine - Thymine
• Adenine - Thymine 
• Adenine - Guanine 
• Guanine -Thymine  

What sugar is found in DNA?

• Sucrose   
• Glucose 
• Deoxyribose 
• Ribose 

Mitochondrial DNA is

• inherited only from the mother 
• in the shape of a triple helix 
• inherited only from the father
• not useful in forensic science
