DNA and RNA resemble each other in possessing

Options

A. Similar pyrimidine bases
B. Similar sugars
C. Ability to replicate
D. Polymers of nucleotides

Answer

To answer the question of how DNA and RNA resemble each other, we can analyze the options provided and determine their similarities step by step.

### Step-by-Step Solution:

1. **Understanding the Components of DNA and RNA**:
- Both DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid) are nucleic acids that are essential for life. They are made up of smaller units called nucleotides.

2. **Identifying Nucleotides**:
- A nucleotide consists of three components:
- A nitrogenous base (which can be purines or pyrimidines)
- A pentose sugar (deoxyribose in DNA and ribose in RNA)
- A phosphate group

3. **Examining the Options**:
- **Option A: Similar Pyrimidine Bases**:
- DNA contains cytosine (C) and thymine (T) as pyrimidines, while RNA contains cytosine (C) and uracil (U). This means they do not share the same pyrimidine bases, making this option incorrect.

- **Option B: Similar Sugars**:
- DNA has deoxyribose sugar, and RNA has ribose sugar. Since the sugars are different, this option is also incorrect.

- **Option C: Ability to Replicate**:
- DNA can replicate in all cellular organisms, while RNA replication occurs naturally only in some viruses. Therefore, this option does not accurately reflect a similarity.

- **Option D: Polymers of Nucleotides**:
- Both DNA and RNA are polymers made up of nucleotides. Each nucleotide in both DNA and RNA consists of a nitrogenous base, a pentose sugar, and a phosphate group. This structural similarity is significant and makes this option correct.

4. **Conclusion**:
- The correct answer is **Option D: Polymers of Nucleotides**. This is the primary similarity between DNA and RNA.
