Biological Molecules

Question 1

Explain how the structure of DNA is related to its function

Answer 1

• DNA contains a sugar phosphate backbone and is double stranded which provides strength and stability to DNA
• has a double helix structure so compact
• is a long molecule so can store lots of information
• base sequence of DNA codes for amino codes
• double stranded so DNA replication can occur semi conservatively
• weak hydrogen bonds between bases for strand separation
