Which of the following is responsible for the heredity character of cell?

Options

A. RNA
B. DNA
C. Proteins
D. Hormones

Answer

**Step-by-Step Solution:**

1. **Identify the Options**: The question provides four options: RNA, DNA, proteins, and hormones. We need to determine which of these is responsible for the heredity character of a cell.

2. **Understand the Role of DNA**: DNA stands for deoxyribonucleic acid. It is the molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses.

3. **Function of DNA in Heredity**: DNA is responsible for storing and transferring genetic information. It contains the instructions necessary for an organism to develop, survive, and reproduce. This genetic information is passed from parents to offspring, which is the basis of heredity.

4. **Eliminate Incorrect Options**:
- **RNA (Ribonucleic Acid)**: While RNA plays a role in protein synthesis and can carry genetic information in some viruses, it is not the primary molecule responsible for heredity in most organisms.
- **Proteins**: Proteins are essential for various cellular functions and structures, but they do not carry genetic information.
- **Hormones**: Hormones are signaling molecules that regulate physiological processes, but they are not involved in the transmission of genetic information.

5. **Conclusion**: Based on the above analysis, DNA is the correct answer as it is the molecule responsible for the heredity character of a cell.

**Final Answer**: DNA
