Unit 6: DNA Replication Quiz 1

Griffith called the process he observed transformation because

• the harmful bacteria had been transformed
• the experiment had been transformed
• the harmless bacteria had been transformed
• the mouse had been transformed

What happened when Griffith injected mice with the harmless, R-strain bacteria alone?

• The bacteria died
• The mouse lived
• The bacteria transformed
• The mouse died

What happened when Griffith injected mice with the heat-killed, S-strain bacteria alone?

• The bacteria died
• The mouse lived
• The bacteria transformed
• The mouse died

Griffith’s experiments advanced the study of genetics by proving that

• there is a chemical that contains genetic information that can be passed from one organism to another
• bacteria can make people sick by infecting them with a chemical that contains genetic information
• the bacteria that can make mice sick are the same bacteria that can be grown in culture dishes in a laboratory
• genetic information can be passed from parents to their offspring during sexual reproduction

What stores genetic information in a cell?

• DNA
• carbohydrates
• proteins
• amino acids

How is DNA like a book?

• DNA has stored information, that can be copied and passed on
• DNA has information wrapped in an identifying cover
• DNA has information that is periodically updated
• DNA has information organized with an kind of index

This figure shows the structure of

• a DNA molecule
• a RNA molecule
• an amino acid
• a protein

Label X is pointing to what structure?

• a protein
• a nucleotide
• RNA
• a phosphate

Which of the following is a nucleotide found in DNA?

• deoxyribose + phosphate group + cytosine
• adenine + phosphate group + thymine
• deoxyribose + phosphate group + polymerase
• cytosine + phosphate group + guanine

Because of base pairing in DNA, the percentage of 

• adenine molecules in DNA is much greater than the percentage of thymine molecules
• thymine molecules in DNA is about equal to the percentage of adenine molecules
• adenine molecules in DNA is about equal to the percentage of guanine molecules
• cytosine molecules in DNA is much greater than the percentage of guanine molecules
