• 2, 3, 1, 4
• 3, 4, 1, 2

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

A process in which DNA has the unique ability to make an exact copy of itself.

• Replication
• Translation
• Transcription

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
