Adenylic acid is

Options

A. Adenine+ribose+phosphate
B. adenine+deoxyribose+phosphate
C. Adenosine+sugar
D. Adenine+sugar

Answer

### Step-by-Step Solution for the Question: "Adenylic acid is"

1. **Definition of Adenylic Acid**:
- Adenylic acid is a nucleotide that is primarily found in RNA. It is also known as adenosine monophosphate (AMP).

2. **Components of a Nucleotide**:
- A nucleotide consists of three main components:
- A nitrogenous base
- A sugar (either ribose for RNA or deoxyribose for DNA)
- A phosphate group

3. **Identifying the Nitrogenous Base**:
- In the case of adenylic acid, the nitrogenous base is adenine.

4. **Identifying the Sugar**:
- Since adenylic acid is a component of RNA, the sugar present is ribose.

5. **Identifying the Phosphate Group**:
- Adenylic acid has one phosphate group, which is essential for its classification as a nucleotide.

6. **Conclusion**:
- Therefore, adenylic acid (or adenosine monophosphate) can be represented as:
- Adenine (nitrogenous base) + Ribose (sugar) + Phosphate (phosphate group).

### Final Answer:
Adenylic acid is a nucleotide composed of adenine, ribose, and a phosphate group.
