Let's break down why:
* Sugar: DNA contains deoxyribose sugar, while RNA contains ribose sugar. This is a key difference.
* Bases: DNA uses thymine (T), while RNA uses uracil (U).
* Structure: DNA is typically double-stranded, while RNA is typically single-stranded.
* Function: DNA serves as the blueprint for life, storing genetic information. RNA plays a role in protein synthesis and other cellular processes.
The phrasing "except" implies that there is one way in which RNA and DNA are NOT different. That's not true.
Let me know if you'd like more detail on any of these differences!
