Resource summary

Question Answer
Sugar phosphate backbone and double helix structure Provides strength and stability Protects information coded in the bases and hydrogen bonding between bases
Long molecule Can store a lot of information
Helix structure Compact
Base sequence codes for amino acids and therefore protiens
Double stranded allows semi conservative replication because each strand can act as a template
Complementary base pairings Allows accurate replication
Hydrogen bonds between bases are weak easily broken and seperation of strands for semi conservative replication
Many hydrogen bonds in the whole molecule Strong and stable molecule
