Polymer of deoxyribonucleotides is

Options

A. DNA
B. RNA
C. Both (1) & (2)
D. None

Answer

**Step-by-Step Solution:**

1. **Understanding the Terminology**: The question asks for the polymer of deoxyribonucleotides. It is important to know what deoxyribonucleotides are. They are the building blocks of DNA and consist of a deoxyribose sugar, a phosphate group, and a nitrogenous base.

2. **Identifying the Components**: Each deoxyribonucleotide contains:
- A deoxyribose sugar (a 5-carbon sugar)
- A phosphate group
- One of four nitrogenous bases (adenine, thymine, cytosine, or guanine)

3. **Defining a Polymer**: A polymer is a large molecule made up of repeating structural units (monomers). In this case, the repeating units are deoxyribonucleotides.

4. **Recognizing the Polymer of Deoxyribonucleotides**: The polymer formed by linking deoxyribonucleotides together through phosphodiester bonds is known as DNA (deoxyribonucleic acid).

5. **Differentiating from RNA**: It is crucial to differentiate DNA from RNA (ribonucleic acid). RNA is made up of ribonucleotides, which contain ribose sugar instead of deoxyribose. Therefore, RNA is not a polymer of deoxyribonucleotides.

6. **Conclusion**: Since the question specifically asks for the polymer of deoxyribonucleotides, the correct answer is DNA.

**Final Answer**: The polymer of deoxyribonucleotides is DNA.
