Nucleic acids are the polymers of

Options

A. nucleosides
B. nucleotides
C. purine bases
D. aldopentose sugar

Answer

**Step-by-Step Solution:**

1. **Understanding Nucleic Acids:**
- Nucleic acids are essential biomolecules that play a crucial role in genetics and cellular functions. They are classified into two main types: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).

2. **Defining Polymers:**
- A polymer is a large molecule composed of repeating structural units, known as monomers. In the case of nucleic acids, the monomers are nucleotides.

3. **Identifying the Components of Nucleotides:**
- Each nucleotide consists of three components:
- A nitrogenous base (which can be a purine or a pyrimidine)
- A pentose sugar (ribose in RNA and deoxyribose in DNA)
- A phosphate group

4. **Connecting Nucleotides to Nucleic Acids:**
- Nucleotides link together through phosphodiester bonds to form long chains, which are the nucleic acids. Thus, nucleic acids are linear polymers made up of nucleotides.

5. **Conclusion:**
- Therefore, the answer to the question "Nucleic acids are the polymers of" is **nucleotides**.
