Nucleic acids are made of

Options

A. small molecules
B. dipeptides
C. long chain polymers of nucleotides
D. polypeptides

Explanation

**Step-by-Step Solution:**

1. **Understanding Nucleic Acids**: Nucleic acids are large biomolecules essential for all known forms of life. They are primarily involved in the storage and expression of genetic information.

2. **Composition of Nucleic Acids**: Nucleic acids are made up of smaller units called nucleotides. Therefore, we can say that nucleic acids are polymers of nucleotides.

3. **Structure of Nucleotides**: Each nucleotide consists of three components:
- A **pentose sugar** (which can be ribose in RNA or deoxyribose in DNA).
- A **phosphate group**.
- A **nitrogenous base** (which can be adenine, guanine, cytosine, thymine, or uracil).

4. **Formation of Nucleic Acids**: When nucleotides link together through phosphodiester bonds (between the phosphate group of one nucleotide and the sugar of another), they form long chains, which are the nucleic acids.

5. **Conclusion**: Thus, nucleic acids are defined as long chain polymers of nucleotides.

**Final Answer**: Nucleic acids are made of long chain polymers of nucleotides.
