* Sugar-Phosphate Backbone: This forms the structural framework of the DNA molecule. It consists of alternating sugar (deoxyribose) and phosphate groups.
* Deoxyribose Sugar: This is a five-carbon sugar molecule that is linked to the phosphate groups.
* Phosphate Group: This is a negatively charged group that links the sugar molecules together.
These components are linked together by phosphodiester bonds, creating a long, continuous chain. The sugar-phosphate backbone is negatively charged, giving DNA its overall negative charge.
Here's a simple analogy: Imagine a ladder. The sides of the ladder are like the sugar-phosphate backbones, and the rungs are like the base pairs.
