Final answer:
Telomeres are crucial for protecting chromosomes from deterioration, preventing them from sticking together, and preserving genetic information during cell division. The answer is (D) I, II, and III.
Step-by-step explanation:
Telomeres are essential structures located at the ends of linear chromosomes. They serve multiple functions, including: Protection of the chromosome from deterioration, which is crucial as cells divide Prevention of chromosomes from sticking together, ensuring proper segregation during cell division Preventing the loss of genetic information with each round of replication, which is a fundamental aspect of cellular reproduction.
The enzyme known as telomerase plays a significant role in maintaining telomere length, adding repetitive DNA sequences to the ends of chromosomes and thus preventing their degradation over time. This process is indispensable for germ cells and some adult stem cells, and contributes to cellular longevity and genomic stability.
