Function of telomeres in nucleus:

Options

A. Pole ward movement
B. To initiate the RNA synthesis
C. To seal the end of Chromosome
D. To recognize the homologous chromosome

Answer

### Step-by-Step Solution:

1. **Understanding Telomeres**:
- Telomeres are repetitive DNA sequences located at the ends of chromosomes. They play a crucial role in protecting the chromosome ends from deterioration.

2. **Functions of Telomeres**:
- The primary function of telomeres is to prevent the loss of important genetic information during DNA replication. Each time a cell divides, a small portion of the telomere is lost. Telomeres help to ensure that the essential coding regions of DNA are preserved.

3. **Role of Telomerase**:
- The enzyme telomerase adds repetitive nucleotide sequences to the telomeres, thereby extending their length and compensating for the loss that occurs during cell division. This is particularly important in stem cells and cancer cells, which divide frequently.

4. **Analyzing the Options**:
- a. **Pole inward movement**: This is not related to the function of telomeres.
- b. **To initiate RNA synthesis**: This is not a function of telomeres; RNA synthesis is initiated by promoters and not by telomeres.
- c. **To seal the end of chromosome**: This is a correct function of telomeres as they prevent chromosomes from fusing with each other and protect the ends from degradation.
- d. **To recognize the homologous chromosomes**: This is not a function of telomeres; homologous chromosomes are recognized by other mechanisms during meiosis.

5. **Conclusion**:
- Based on the analysis, the correct answer is **option C: to seal the end of chromosome**.
