Hayflick Limit: Cellular Senescence and its Role in Ageing - UPSC Science And Technology
What is Hayflick Limit: Cellular Senescence and its Role in Ageing in UPSC Science And Technology?
Hayflick Limit: Cellular Senescence and its Role in Ageing is a key topic under Science And Technology for UPSC Civil Services Examination. Key points include: The <strong>Hayflick Limit</strong> states that <strong>somatic cells</strong> can only divide a finite number of times (40-60) before stopping.. This cessation of division is called <strong>cellular senescence</strong>, and its accumulation contributes to aging.. The discovery challenged the belief that aging was solely due to external factors, introducing the concept of an <strong>inherent cellular clock</strong>.. Understanding this topic is essential for both UPSC Prelims and Mains preparation.
