What does telomerase do for aging? The cellular clock revealed

Every time one of your cells divides, the protective caps on its chromosomes, known as telomeres, get a little shorter. This fundamental process, known as cellular senescence, is a key driver of biological aging. Understanding **what does telomerase do for aging** is crucial, as this enzyme works to counter this shortening and prolong the lifespan of your cells.

How does DNA replication relate to aging?

Every time a cell divides, it faces the risk of DNA replication errors and incomplete copying, factors that directly influence the aging process. This phenomenon, known as replication stress, is now considered a fundamental driver of cellular senescence and organismal aging. In this comprehensive overview, we explore how imperfections in DNA duplication contribute to the gradual biological decline we experience throughout life.

What is telomere shortening theory?

In 1961, biologist Leonard Hayflick discovered that human cells have a limited number of times they can divide, a phenomenon now known as the Hayflick limit. This landmark observation laid the groundwork for understanding the telomere shortening theory, a prominent explanation for cellular aging.

What is the telomere theory of aging?

In 1961, biologist Leonard Hayflick discovered that normal human cells have a limited capacity to divide before they stop replicating, a phenomenon known as the Hayflick limit. At the heart of this observation lies the telomere theory of aging, which offers a compelling explanation for how our cellular lifespan is regulated.
