DNA resembles RNA as both have

Options

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

Answer

To answer the question "DNA resembles RNA as both have," we will break down the similarities and differences between DNA and RNA step by step.

### Step 1: Identify the Basic Structure
Both DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid) are classified as nucleic acids. They are both polymers made up of smaller units called nucleotides.

**Hint:** Think about the building blocks of DNA and RNA.

### Step 2: Understand the Composition of Nucleotides
Each nucleotide consists of three components:
1. A nitrogenous base
2. A sugar molecule
3. A phosphate group

**Hint:** Recall what makes up a nucleotide and how these components are structured.

### Step 3: Compare the Nitrogenous Bases
Both DNA and RNA contain four types of nitrogenous bases:
- DNA: Adenine (A), Thymine (T), Guanine (G), Cytosine (C)
- RNA: Adenine (A), Uracil (U), Guanine (G), Cytosine (C)

**Hint:** Focus on the similarities and differences in the nitrogenous bases.

### Step 4: Compare the Sugars
The sugar in DNA is deoxyribose, while the sugar in RNA is ribose. This is a key difference between the two.

**Hint:** Remember the specific names of the sugars and how they differ.

### Step 5: Analyze the Ability to Replicate
DNA has the ability to replicate itself, whereas RNA does not have this capability. This is another significant difference.

**Hint:** Consider the functions of DNA and RNA in the cell.

### Conclusion
The primary similarity between DNA and RNA is that they are both nucleic acids composed of nucleotides, which include nitrogenous bases, a sugar, and a phosphate group. Therefore, the answer to the question is that DNA resembles RNA as both have nucleotides.

**Final Answer:** DNA resembles RNA as both have nucleotides.
