Chapter 14 Miller Levine

During replication, which sequence of nucleotides would bond with the DNA sequence TATGA? 

• TATGA
• ATACT
• CACTA
• AGTAT

The scientist(s) responsible for the discovery of bacterial transformation is (are)

• Watson and Crick
• Avery
• Griffith
• Franklin

Which of the following does NOT describe the structure of DNA?

• double helix
• long chain of nucleotides
• contains adenine-guanine pairs
• sugar-phosphate

What did Hershey and Chase's work show? 

• Genes are probably made of DNA.
• Genes are probably made of protein.
• Viruses contain DNA but not protein.
• Bacteria contain DNA but not protein. 

The two "backbones" of the DNA molecule consist of

• adenines and sugars.
• phosphates and sugars.
• adenines and thymines.
• thymines and sugars. 

When prokaryotic cells copy their DNA, replication begins at 

• one point on the DNA molecule. 
• two points on opposite ends of the DNA molecule. 
• dozens to hundreds of points along the molecule. 
• opposite ends of the molecule. 

Compared to eukaryotic cells, prokaryotic cells contain

• much more DNA. 
• much less DNA. 
• twice as much DNA. 
• the same amount of DNA. 

The process by which one strain of bacterium is apparently changed into another strain is called

• transcription.
• transformation.
• duplication.
• replication.

Bacteriophages are 

• a form of bacteria.
• enzymes.
• coils of DNA.
• viruses.

Before DNA could be shown to be the genetic material in cells, scientists had to show that it could 

• tolerate high temperatures. 
• carry and make copies of information.
• be modified in response to environmental conditions. 
• be broken down into small subunits.
