If we think of DNA as a ladder, which parts are the sides of the ladder?

• the nitrogenous base pairs

• the phosphate-sugar backbone

• the genes

• the phospholipid bilayer

Which sequence of DNA bases would pair with this partial strand
ATG TGA CAG

• ATG TGA CAG

• TAC ACT GTC

• GTA AGT GAC

• CAT TCA CTG

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
