Which of the following is the carrier of genetic information?

Options

A. proteins
B. amino acids
C. DNA
D. carbohydrate

Answer

To answer the question "Which of the following is the carrier of genetic information?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: First, we need to identify the options provided in the question. Common carriers of genetic information include DNA, RNA, proteins, amino acids, and carbohydrates.

2. **Understand the Role of Nucleic Acids**: Nucleic acids, which include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are the primary carriers of genetic information in living organisms.

3. **Focus on DNA**: In most higher organisms, DNA is the main carrier of genetic information. It encodes the genetic instructions necessary for the development, functioning, growth, and reproduction of all known organisms.

4. **Consider Exceptions**: While DNA is the primary carrier in most organisms, some viruses use RNA as their genetic material. However, for the majority of organisms, DNA is the key carrier.

5. **Eliminate Other Options**:
- **Proteins**: While proteins are essential for various functions in the body, they do not carry genetic information.
- **Amino Acids**: These are the building blocks of proteins and do not carry genetic information themselves.
- **Carbohydrates**: These serve primarily as energy sources and structural components, not as carriers of genetic information.

6. **Conclude the Answer**: Based on the above reasoning, the correct answer to the question is that DNA is the carrier of genetic information.

### Final Answer:
The carrier of genetic information is DNA.
