Telomere repetitive DNA sequences control the function of eukaryote chromosomes because they

Options

A. Act as replicons
B. Are RNA transciption initiator
C. Help chromosome pairing
D. Prevent chromosome loss

Answer

### Step-by-Step Solution:

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

2. **Protection of DNA**: The primary function of telomeres is to provide protection to the DNA. They act like caps on shoelaces, preventing the ends of chromosomes from fraying and being damaged by harmful enzymes.

3. **Preventing Chromosome Loss**: Telomeres prevent the loss of genetic information during DNA replication. Without telomeres, important coding regions of the DNA could be lost when the cell divides.

4. **Role in Cell Division**: During cell division, telomeres help ensure that chromosomes do not tangle or fuse with one another. This is crucial for maintaining the integrity of the genetic material.

5. **Non-coding Function**: It is important to note that telomeres do not code for proteins. Instead, they consist of repetitive sequences that serve protective functions.

6. **Facilitating Chromosome Pairing**: Telomeres assist in the proper pairing of chromosomes during meiosis, ensuring that genetic material is accurately distributed to daughter cells.

7. **Conclusion**: In summary, telomeres are essential for maintaining chromosome stability, preventing degradation, facilitating cell division, and ensuring the proper distribution of genetic material during cell division.
