Select true or false statement :
Deoxythymidine is monomer nucleotide of DNA.

Answer

To determine whether the statement "Deoxythymidine is a monomer nucleotide of DNA" is true or false, let's break it down step by step.

### Step 1: Understand the Structure of DNA
DNA (Deoxyribonucleic Acid) is a polymer made up of repeating units called nucleotides. Each nucleotide consists of three components:
1. A nitrogenous base
2. A sugar molecule (deoxyribose in the case of DNA)
3. A phosphate group

### Step 2: Identify the Components of a Nucleotide
In DNA, the nitrogenous bases are:
- Adenine (A)
- Guanine (G)
- Cytosine (C)
- Thymine (T)

The sugar component in DNA is deoxyribose, and the phosphate group is the same for all nucleotides.

### Step 3: Define Deoxythymidine
Deoxythymidine refers specifically to the nucleotide that contains the nitrogenous base thymine (T), along with deoxyribose and a phosphate group. Therefore, deoxythymidine is indeed one of the building blocks (monomers) of DNA.

### Step 4: Conclusion
Since deoxythymidine is a nucleotide that forms part of the structure of DNA, the statement "Deoxythymidine is a monomer nucleotide of DNA" is true.

### Final Answer
**True**
