DNA structure related to function

• Why does DNA have a long, coiled and compact structure?


  can store a lot of genetic material in a small space within a cell
• What is the significance of the sugar phosphate backbone?

  Provides strength and stability to protect the nitrogen containing organic base
• Why are complimentary base pairings important in DNA?

  enable information to be accurately replicated
• What are 2 benefits of hydrogen bonds in DNA?

  - individually weak so can be easily broken by Helicase to produce template strands during DNA replication

  - many hydrogen bonds give the molecule stability
• Why is it useful that DNA is double stranded?

  Both strands can act as template strands during semi conservative replication
