Which of the following type of phytohormones resemble the nucleic acids in some structural aspects

Options

A. Cytokinins
B. Auxins
C. Gibberellins
D. Abscisic acid

Answer

To solve the question "Which of the following type of phytohormones resemble the nucleic acids in some structural aspects?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- Cytokinins
- Auxins
- Gibberellins
- Abscisic acid

2. **Understand Phytohormones**: Phytohormones are chemical messengers in plants that regulate growth and development. Each type has a different structure and function.

3. **Analyze Each Option**:
- **Cytokinins**: These are derivatives of purines, specifically adenine. Since adenine is a component of nucleic acids (DNA and RNA), cytokinins resemble nucleic acids structurally.
- **Auxins**: These are primarily derived from amino acids, particularly indole compounds. They do not resemble nucleic acids.
- **Gibberellins**: These are derived from terpenes and do not share structural similarities with nucleic acids.
- **Abscisic Acid**: This hormone is derived from carotenoids, which are pigments, and does not resemble nucleic acids.

4. **Conclusion**: Based on the analysis, the only phytohormone that resembles nucleic acids in some structural aspects is **Cytokinins**.

### Final Answer:
The correct answer is **Cytokinins**.
