How does sugar phosphate backbone help dna structure?
Gives strength
How does coiling Of dna help it’s structure?
Gives compact shape
How does dna being long help the structure?
Allows storage of large amounts of information
What does complementary base pairing allow to happen?
Allows information to be replicated rapidly
