In nucleic acid the sequence is?

Options

A. Phosphate, Base, Sugar
B. Sugar, Base, Phosphate
C. Base, Sugar, Phosphate
D. Base, Phosphate, Sugar

Explanation

To determine the sequence in nucleic acids, we need to understand the components that make up nucleotides, which are the building blocks of nucleic acids like DNA and RNA.

### Step-by-Step Solution:

1. **Identify the Components of Nucleotides**:
- Nucleotides consist of three main components: a nitrogenous base, a sugar, and a phosphate group.

2. **Types of Nitrogenous Bases**:
- There are two types of nitrogenous bases:
- Purines (adenine and guanine)
- Pyrimidines (cytosine, thymine, and uracil)

3. **Types of Sugars**:
- The sugar component can either be ribose (found in RNA) or deoxyribose (found in DNA).

4. **Sequence Arrangement**:
- The sequence of a nucleotide is typically arranged as follows:
- First comes the nitrogenous base, followed by the sugar, and then the phosphate group.

5. **Correct Sequence**:
- Therefore, the correct sequence in nucleic acids is:
- Base → Sugar → Phosphate

6. **Choosing the Correct Option**:
- From the provided options, the sequence that matches this arrangement is "Base Sugar Phosphate".

### Final Answer:
The correct sequence in nucleic acids is **Base Sugar Phosphate**.
