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

Encoded DNA; the portion of DNA with directions to build molecules is called:

•  Exons      
• Polymorphism
• Primers
• Introns 

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

Un-encoded DNA that functions in gene splicing is called:

• Introns
• Nuclear DNA
• DNA probe 
• Exons

The process of DNA fingerprinting was invented by:

• Jeffreys 
• Roseland
• Crick
• Watson 

DNA fingerprinting was first invented for the purpose of:

• Paternity testing  
• Identifying victims of war
• Studying biodiversity and evolution of species 
• Diagnosing and treating diseases 

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
