Nucleic acids are the polymers of

Options

A. nucleosides
B. nucleotides
C. bases
D. sugars

Explanation

**Step-by-Step Solution:**

1. **Understanding Nucleic Acids**: Nucleic acids, such as DNA and RNA, are essential biomolecules that carry genetic information in living organisms. They are classified as polymers.

2. **Defining Polymers and Monomers**: Polymers are large molecules made up of repeating units called monomers. To identify the monomer of nucleic acids, we need to determine what basic unit is repeated to form nucleic acids.

3. **Analyzing the Options**: The question provides four options: nucleosides, nucleotides, bases, and sugars. We need to evaluate each option to find the correct monomer.

4. **Understanding Bases**: Bases are nitrogenous compounds like adenine and guanine. They are one component of nucleotides but are not the complete monomer.

5. **Understanding Nucleosides**: A nucleoside consists of a base attached to a sugar (either ribose or deoxyribose). While nucleosides are important, they are not the complete building blocks of nucleic acids.

6. **Understanding Nucleotides**: A nucleotide is formed when a nucleoside (base + sugar) is further combined with a phosphate group. Nucleotides are the actual monomers that link together to form nucleic acids.

7. **Conclusion**: Since nucleotides consist of a base, a sugar, and a phosphate group, they are the repeating units that make up nucleic acids. Therefore, the correct answer to the question is that nucleic acids are polymers of **nucleotides**.

**Final Answer**: Nucleic acids are the polymers of **nucleotides**.
