Biology 1B Final Review

Which of these is not a role of DNA? 

• copies info
• deletes info
• stores info
• transfers info

What is the monomer of nucleic acids like DNA? 

• nucleotide
• amino acid
• protein
• monosaccharide

Which of these is not a building block of the nucleotide? 

• amino acid
• phosphate group
• sugar
• nitrogenous bases (A, T, C, G, U)

In our candy DNA model, we used marshmallows to connect the two strands of DNA together in the middle. What did that represent? 

• hydrogen bond
• covalent bond
• sugar phosphate backbone
• nitrogenous bases (information)

Why are Watson and Crick important to the story of DNA? 

• They developed a correct model of DNA
• The took XRay photos of DNA
• They knew that each A matched with T, and each C matched with G
• They made mice sick by giving them bacteria to provide evidence for DNA transformation

If you were to analyze a strand of DNA and you found that there was 30% Adenine, which of the following statements can you infer?

• There is 30% Guanine
• There is 30% Cytosine
• There is 20% Thymine
• There is 20% Cytosine

Which enzyme is responsible for "unzipping the genes" before DNA replication? 

• helicase
• DNA primase
• DNA polymerase
• RNA polymerase

What is true about DNA replication?

• Each daughter DNA molecule has one old strand and one new strand
• Each daughter DNA molecule has a mixture of old and new DNA on both strands
• The two daughter DNA molecules are different: one is completely old and one is completely new
• The two daughter DNA molecules are both completely new

Which enzyme is responsible for adding new nucleotides to the growing DNA polymer in DNA replication? 

• DNA polymerase
• RNA polymerase
• DNA primase
• helicase

Which of these is not a correct statement that differentiates DNA and RNA? 

• RNA and DNA have the same nitrogenous bases
• RNA is single stranded and DNA is double stranded
• DNA stays in the nucleus while RNA versions can leave the nucleus
• RNA's sugar= ribose
  DNA sugar= deoxyribose
