Describe how DNA is well-adapted to being a molecule for conserved information storage

DNA is a long, large molecule, which allows a lot of information to be stored within in. It has a sugar-phosphate backbone, which protects it from physical and chemical damage as the phospho-diester linkages are very strong. It contains many hydrogen bonds between the two strands of the molecule, and due to there being many bonds the molecule is very stable as breaking so many of them requires a lot of energy, but the hydrogen bonds also allow the strands to be "unzipped" to allow reading of the information. The double strands also allow semi-conservative replication, which means the information can be copied with minimal chance of corruption. Being made up of bases, the information is stored using a universal code, meaning it can be easily read.
