Key Differences Between RNA and DNA
* Sugar: DNA uses deoxyribose sugar, while RNA uses ribose sugar. This is the most fundamental difference.
* Nitrogenous Bases: DNA uses the bases adenine (A), guanine (G), cytosine (C), and thymine (T). RNA uses adenine (A), guanine (G), cytosine (C), and uracil (U) instead of thymine.
* Structure: DNA is typically double-stranded, forming a helix. RNA is usually single-stranded, though it can fold into complex shapes.
* Function: DNA primarily stores genetic information, while RNA plays a more active role in protein synthesis and other cellular processes.
The "Except" Part
To answer your question completely, I need the list of options that you're considering. Please provide the list of ways RNA and DNA are different, and I can tell you which one is NOT a difference.
Example:
Let's say the list of options is:
1. RNA uses ribose sugar, while DNA uses deoxyribose sugar.
2. RNA is usually single-stranded, while DNA is double-stranded.
3. RNA has uracil instead of thymine.
4. RNA is involved in protein synthesis, while DNA is not.
5. RNA is more stable than DNA.
In this example, the answer would be 5. RNA is more stable than DNA. This is incorrect. DNA is actually more stable than RNA due to its lack of an extra hydroxyl group, making it less susceptible to degradation.
