Nucleotides are composed of two types of sugars

Options

A. glucose and ribose
B. glucose and maltose
C. ribose and deoxyribose
D. meltose and deoxyribose

Explanation

To solve the question regarding the composition of nucleotides, we need to understand the basic structure of nucleotides and the types of sugars involved. Here’s a step-by-step breakdown:

### Step 1: Understand the Structure of Nucleotides
Nucleotides are the building blocks of nucleic acids (DNA and RNA). Each nucleotide consists of three components:
1. A nitrogenous base
2. A sugar
3. A phosphate group

### Step 2: Identify the Types of Sugars in Nucleotides
There are two types of sugars found in nucleotides:
- **Deoxyribose**: This sugar is found in DNA (deoxyribonucleic acid).
- **Ribose**: This sugar is found in RNA (ribonucleic acid).

### Step 3: Analyze the Given Options
The question provides multiple options regarding the types of sugars in nucleotides. We need to identify which option correctly lists the two types of sugars:
- Option A: Glucose and Ribose
- Option B: Glucose and Maltose
- Option C: Ribose and Deoxyribose
- Option D: (not specified)

### Step 4: Determine the Correct Answer
From our understanding:
- Glucose is not a sugar found in nucleotides.
- Maltose is a disaccharide and also not found in nucleotides.
- Ribose and Deoxyribose are indeed the correct sugars present in nucleotides.

Thus, the correct option is **Option C: Ribose and Deoxyribose**.

### Conclusion
The answer to the question is that nucleotides are composed of two types of sugars: ribose and deoxyribose.
