RNA differs from DNA in nature of

Options

A. sugar and purines
B. sugar and pyrimidines
C. purines and phosphate
D. sugar and phosphate

Answer

To answer the question "RNA differs from DNA in nature of," we need to analyze the structural components of both RNA and DNA. Here’s a step-by-step solution:

### Step 1: Identify the Components of Nucleotides
Both RNA and DNA are made up of nucleotides, which consist of three main components:
- A pentose sugar
- A nitrogenous base
- A phosphate group

### Step 2: Compare the Sugars
- In RNA (Ribonucleic Acid), the sugar is **ribose**.
- In DNA (Deoxyribonucleic Acid), the sugar is **deoxyribose**.

This difference in sugar is a key distinguishing feature between RNA and DNA.

### Step 3: Compare the Nitrogenous Bases
- RNA contains the nitrogenous bases: **adenine (A)**, **guanine (G)**, **cytosine (C)**, and **uracil (U)**.
- DNA contains the nitrogenous bases: **adenine (A)**, **guanine (G)**, **cytosine (C)**, and **thymine (T)**.

### Step 4: Classify the Bases
- Both RNA and DNA contain the purines **adenine** and **guanine**.
- The pyrimidines differ: RNA has **cytosine** and **uracil**, while DNA has **cytosine** and **thymine**.

### Conclusion
From the analysis, we can conclude that RNA differs from DNA primarily in the nature of:
1. The sugar (ribose in RNA vs. deoxyribose in DNA)
2. The nitrogenous base (uracil in RNA vs. thymine in DNA)

Thus, the answer to the question is that RNA differs from DNA in the nature of its **sugar and nitrogenous bases**.
