Make up Chapter 10

The method of DNA replication is known as:

• Semi-conservative

• Conservative

• Dispersive

• Complementary

In a molecule of double-stranded DNA, the amount of Adenine present is always equal to the amount of

• cytosine
• guanine
• thymine
• uracil

In his work with pneumonia-causing bacteria and mice, Griffith found that

• the protein coat from S cells transformed R cells
• Heat killed S cells caused pneumonia
• a substance from S cells transformed R cells
• bacteriophages injected DNA into bacteria

What was the most important concept demonstrated by Griffith's experiment?

• Dead bacteria donated something to living bacteria
• Heat destroys the ability of the bacteria to kill the mouse
• Proteins are the primary source of genetic information

In Griffith's experiment DNA from S strain bacteria caused R strain bacteria to be transformed.

• True
• False

What were the results of the Avery, McCarty, Macleod experiment?

• The flask with no protein had no S cells
• The flask with no RNA had no S cells
• The flask with no DNA had no S cells

What was the conclusion that Avery, McCarty, and MacLeod drew from their results?

• DNA is responsible for transforming type S cells into type S cells
• DNA is responsible for transforming type R cells into type S cells
• DNA is responsible for transforming type S cells into type R cells

Who determined that DNA was the transforming factor in Griffith's experiments?

• Frederick Griffith

• Rosalind Franklin

• Alfred Chase

• Oswald Avery

Which strain of S. pneumoniae was virulent (pathogenic)? 

• R strain
• S strain
• Both
• Neither

What organism was Griffith using when he discovered that a harmless strain of bacteria could transform into a lethal strain of bacteria?
