DNA H

What is a series of events a cell goes through as they grow and divide?

• Cell Division

• Cell Cycle

• Cytokinesis

• Mitosis

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
