Here's a breakdown:
* Sugar: This is a five-carbon sugar. In DNA, the sugar is deoxyribose, while in RNA, it's ribose.
* Phosphate Group: A phosphate group (PO43-) is attached to the 5' carbon of one sugar and the 3' carbon of the next sugar. This creates a repeating pattern of sugar-phosphate-sugar-phosphate, forming the backbone of the molecule.
Key Differences:
* Deoxyribose vs. Ribose: The only difference between deoxyribose and ribose is that deoxyribose lacks an oxygen atom at the 2' carbon position. This seemingly small difference has significant implications for the structure and function of DNA and RNA.
* Structure: DNA is a double-stranded helix, while RNA is usually single-stranded.
