DNA Replication

What is the shape of DNA?

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

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

DNA replication results in two DNA molecules,

• each one with two original strands
• each one with two new strands
• each one with one new strand and one original strand

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
