What is the longest stage of the cell cycle called?

• Cytokinesis
• M phase
• Interphase
• G1 Phase

During what stage does the G₁, S and G₂ phases happen?

• Interphase
• M phase
• Mitosis
• Cytokinesis

Which enzyme has the job of unzipping the double helix?

• Helicase
• Polymerase
• Ligase
• Primerase

What is the shape of DNA?

• Double helix
• Triple helix
• Flat, bilayer
• Three-pronged rigid ladder

Sometimes, DNA is called "semi-conservative." Why might this be?

• The old strand is "conserved" and used to make the new strands
• Uracil is "conserved" in that it is only used to make the new strands
• ATP is "conserved" via the usage of facilitated diffusion
• Ligase is "conserved" in that it is denatured by the process

Replicate the following strand of DNA: 
AATCATGGA

• AATCATGGA
• TTAGTACCT
• UUAGUACCU
• GGATAUCUA

The bonds that hold the two strands of DNA together come from...

• the attraction of phosphate groups 
• strong bonds between  bases and sugars
• carbon to carbon bonds in the sugar
• weak hydrogen bonds between the bases

The DNA nucleotide is composed of three parts. Which two components make up the nucleotide backbone?

• ribose sugar and base
• ribose sugar and phosphate group
• nitrogen base and deoxyribose sugar
• deoxyribose sugar and phosphate group
  

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy
