Telomeres-Post Research Questions

A. Basic Understanding of Telomeres

1. 1. What are telomeres, and what is their primary function in cells?

Describe the structure of a telomere.

• A region of the chromosome that contains the centromere

• A repetitive nucleotide sequence at the end of a chromosome

• A protein that regulates gene expression

• A segment of DNA that codes for a specific protein

A. Basic Understanding of Telomeres

1. 2. How do telomeres change with age?

A. Basic Understanding of Telomeres

1. 3. What is the role of telomerase in maintaining telomere length?

B. Telomeres and Aging

1. 1. How does telomere shortening contribute to the aging process?

B. Telomeres and Aging

1. 2. Are there any lifestyle factors that can influence telomere length and aging? (e.g., diet, exercise, stress)

How does the enzyme telomerase help maintain telomere length?

• Telomerase causes mutations in the nucleotide sequences of telomeres.

• Telomerase adds repetitive nucleotide sequences to the ends of chromosomes.

• Telomerase breaks down repetitive nucleotide sequences on the ends of chromosomes.

• Telomerase has no effect on telomere length.

B. Telomeres and Aging

1. 3. Can telomere length be used as a biomarker for biological age?

C. Telomeres and Disease

2. 1. How are telomeres linked to age-related diseases like cancer, heart disease, and neurodegenerative disorders?

C. Telomeres and Disease

1. Rudi, a 65-year-old man, has been experiencing various age-related health issues. After researching, he learns about the role of telomeres in cellular aging.

2. 2. Can interventions that target telomeres be used to prevent or treat age-related diseases that Rudi is facing?
