DNA's suitability for its function stems from its stability, the ability of its strands to separate via hydrogen bonds for replication, its capacity to store extensive genetic information, and the protection of its base sequence by the sugar-phosphate backbone.
DNA is adapted for its function as a stable molecule that rarely mutates, its strands can separate due to weak H-bonds for replication, it carries vast genetic information, and the base sequence is protected by the sugar-phosphate backbone.
| Front | Why is DNA adapted to carry out its function |
|---|---|
| Back | It is a very stable structure and can pass through generations, rarely without a mutation. The 2 separate strands are joined only by H-Bonds, this allows strands to separate during DNA replication. It is a large molecule, therefore, carries a large amount of genetic information. By having base pairs inside a helical cylinder of deoxyribose-phosphate backbone, genetic information is protected from being corrupted by outside chemical and physical forces. |
