Q6. How does the Hayflick limit explain the natural constraints on human aging, and what implications does it have for the pursuit of extending human lifespan? Discuss. (250 words)
Difficulty level: Moderate
Reference: The Indian Express
Why the question: Biomedical researcher Leonard Hayflick, who discovered that normal somatic cells can divide (and thus reproduce) only a certain number of times, died on August 1, 2024 at the age of 98. Key demand of the question: To discuss the scientific concept of the Hayflick limit, its role in aging, and the challenges it presents for extending the human lifespan. Directive word: Discuss – Examine the Hayflick limit and explore its implications for aging and the possibilities of overcoming it through scientific advances. Structure of the answer: Introduction: Define the Hayflick limit and explain its significance in aging. Body: Mention the cellular mechanisms underlying the Hayflick limit, including the role of telomeres and telomerase. Mention how this discovery has shaped scientific approaches to lifespan extension and the limitations faced by current technology. Conclusion: Summarize the potential and limitations of overcoming the Hayflick limit in pursuit of human immortality.
