Where do you find the following in DNA, RNA or in both?
(a) ribose, (b) deoxyribose, (c) adenine, (d) uracil, (e) guanine.

Explanation

To determine where the following components are found—DNA, RNA, or both—let's analyze each component step by step:

### Step 1: Identify the presence of ribose
- **Ribose** is a sugar molecule that is found in RNA. It has a hydroxyl group (-OH) attached to the second carbon atom.
- **Answer**: Ribose is found in RNA.

### Step 2: Identify the presence of deoxyribose
- **Deoxyribose** is a sugar molecule that is found in DNA. It differs from ribose by the absence of an oxygen atom on the second carbon (hence "deoxy").
